2015 TV Season: On-the-bubble shows, renewals and cancellations

TV networks are busy taking ratings inventory on show schedules as the time approaches for May's Upfronts, where each major broadcast network will unveil its new season schedule to advertisers in New York.

TheWrap took a close look at how TV shows across each network are performing, placing all the series that have not been renewed or canceled yet into one of three categories: "Close, But Safe," "Flip a Coin" and "About to Burst."

We used demo ratings, total viewers and insider buzz to make our predictions about what stays and what goes.

Our findings suggest that series such as CBS's "CSI" and Fox's "Bones" will probably get another year — but don't hold your breath on ABC's "Revenge" and NBC's "About a Boy." However, the latter two shows have a better chance of returning than others such as Fox's "Weird Loners" and CBS's "Battle Creek."

All numbers below are from Nielsen's data stream, which includes seven-day viewing lifts where available. The numbers were compiled from Sep. 22, 2014 through April 5, 2015. The shows that debuted within the last two weeks may not have delayed viewing numbers included, which by comparison makes them appear weaker than series with earlier premieres.

See TheWrap status report on Bubble Shows and below is a list of each network's shows that have already been renewed or canceled:

Show: "Marvel's Agent Carter"
Network: ABC
Demo Rating: 2.3
Total Viewers: 7.1 million
Why: "Agent Carter" didn't start as hot as "Marvel's Agents of SHIELD," but its rating and audience numbers are good enough to keep it around. Plus, Disney and Marvel do excellent business together. Oddly enough, Marvel is planning a second spinoff from "SHIELD," which could be either a good or bad sign for Carter.

Show: "America's Funniest Home Videos"
Network: ABC
Demo Rating: 1.3
Total Viewers: 6.2 million
Why: The demo ratings are bad, the viewers are OK, but the legacy show is embedded in ABC's Sunday night lineup. Why cancel it now?

Secrets & Lies/ABC

Show: "Secrets & Lies"
Network: ABC
Demo Rating: 2.2
Total Viewers: 7.8 million
Why: The Aussie adaptation actually gets a decent delayed-viewing lift, and has come up some from a slow start. Plus, the show has some star power in Ryan Phillippe and Juliette Lewis.

Show: "The Good Wife"
Network: CBS
Demo Rating: 1.9
Total Viewers: 12.5 million
Why: The legal procedural has surprisingly weak demo ratings, but a good overall audience. That said, the series is beloved by fans and critics and skews upscale — that's good enough for another season.

Show: "CSI: Cyber"
Network: CBS
Demo Rating: 2.3
Total Viewers: 11.7 million
Why: The latest "CSI" spinoff didn't score such a hot start, but its more or less hung in there thanks to delayed viewing. It's been finding footing a bit too as the initial run progresses. The show feels very "now," but is an odd combination of old network/modern technology. Having Patricia Arquette hot off her Oscar win helps, so CBS probably won't throw in the towel yet.

Show: "Hawaii 5-0"
Network: CBS
Demo Rating: 2.0
Total Viewers: 12.5 million
Why: "Hawaii 5-0" does quite well for a Friday show, plus it's sold into syndication and is a proven money maker.

Show: "Blue Bloods"
Network: CBS
Demo Rating: 1.9
Total Viewers: 13.8 million
Why: See everything we said about "Hawaii 5-0," except increase the average viewer total by another 1.3 million.

Show: "iZombie"
Network: CW
Demo Rating: 0.9
Total Viewers: 2.4 million
Why: It's too early to truly call "iZombie," but right now renewal looks likely. File this comic book adaptation under "good chance."

Show: "Bones"
Network: Fox
Demo Rating: 1.9
Total Viewers: 7.4 million
Why: Fox can't cancel BOTH Hart Hanson shows, can they? (Sorry, "Backstrom" — you're on the wrong end of this list.) "Bones" is one of the most solid shows for the network, so long as its stars don't go into hiding, the network can always squeeze out another run of episodes.

Undateable/NBC

Show: "Undateable"
Network: NBC
Demo Rating: 2.3
Total Viewers: 5.8 million
Why: The Season 1 summer show had middling ratings, but NBC has a real shortage of comedies right now. It's hard to predict the future of the Chris D'Elia sitcom right now as Season 2 is in a new calendar … season. NBC seems committed to giving the show a chance, though.

Show: "AD: The Bible Continues"
Network: NBC
Demo Rating: 2.3
Total Viewers: 9.7 million
Why: The show got its start on Easter, which was just smart scheduling. It's way too early to predict, but right now, solely based on the premiere numbers, you have to presume this one is set up to continue.

Mysteries of Laura/NBC

Show: "Mysteries of Laura"
Network: NBC
Demo Rating: 1.5
Total Viewers: 8.5 million
Why: "Laura" doesn't score in the demo, but skews old enough to pull in 8.6 million viewers — which is pretty good for NBC primetime. Plus, NBC is pretty loyal to its Will & Grace" stars, right Sean Hayes?

Show: "Forever"
Network: ABC
Demo Rating: 1.7
Total Viewers: 6.9 million
Why: "Forever" seemed doomed from the get-go, but seven million viewers, an upscale audience and some internal support may be enough bring it back. We just wouldn't bet on it because of its lousy demo performance. Plus, many people think it's already been canceled — and that's never a good sign.

ABC

Show: "Revenge"
Network: ABC
Demo Rating: 1.9
Total Viewers: 6.8 million
Why: The numbers aren't great, but also aren't terrible. Entering a potential fifth season however oftentimes equals contract negotiations. Let's just wait and see on this one.

Show: "American Crime"
Network: ABC
Demo Rating: 1.8
Total Viewers: 7.6 million
Why: "American Crime" had a disappointing start, but does OK in total viewers. Still, this is a limited series, so ABC could just let it go without technically canceling it. That said, don't think for a second that "limited run" shows won't get sophomore seasons if they do well freshman year.

Show: "Resurrection"
Network: ABC
Demo Rating: 2.9
Total Viewers: 6.9 million
Why: The numbers for "Resurrection" could be worse, but could be better. This show had a really hot start, but the story never paid off. It's probably time to let this one go.

Show: "The Following"
Network: Fox
Demo Rating: 1.9
Total Viewers: 5.5 million
Why: The show just hit another new low. In reality, it probably should have been canceled a year ago. That said, Kevin Bacon is still a pretty good TV get and the series had a rock solid Season 1.

Fox

Show: "The Mindy Project"
Network: Fox
Demo Rating: 1.4
Total Viewers: 2.9 million
Why: "Mindy" is a very funny show and critics dig it. "New Girl" was just renewed, so its Tuesday night counterpart could potentially come back despite low ratings. However, the fact that "Mindy" comes from an outside studio doesn't help its chances.

Show: "One Big Happy"
Network: NBC
Demo Rating: 1.4
Total Viewers: 4.6 million
Why: While it's admittedly early to judge its longevity, the Ellen DeGeneres-produced show does feels somewhat ripe for being wiped out like it never happened. But once again, NBC has a big need for comedies, and "One Big Happy" can be filed under "so far, so good (enough)."

Show: "Repeat After Me"
Network: ABC
Demo Rating: 1.2
Total Viewers: 3.9 million
Why: Just look at the numbers — they're not good. It's another DeGeneres show, but this unscripted one feels like a B-list celebrity version of "Impractical Jokers" and "Deal With It," alongside many more. At least it's cheap to make, right?

Show: "Galavant"
Network: ABC
Demo Rating: 1.9
Total Viewers: 6.5 million
Why: Another "limited series," which could save it from ever technically being canceled. That said, the show performed better than many expected. It has in-house political backing, but "Galavant" came with a hefty price tag. If they can make it cheaper, they may bring it back.

Battle Creek/CBS

Show: "Battle Creek"
Network: CBS
Demo Rating: 1.3
Total Viewers: 8.6 million
Why: Ratings-wise, this show was D.O.A., and has only gotten worse. CBS has so many hits, expect the Les Moonves episode to chalk this one up as an obvious "miss" and lose it.

Show: "Weird Loners"
Network: Fox
Demo Rating: 0.7
Total Viewers: 1.9 million
Why: The show had a terrible debut for a comedy that probably should never have been made. Fox has excellent comedies — high rated or not — so they don't need this loser.

Marry Me/NBC

Show: "Marry Me"
Network: NBC
Demo Rating: 1.5
Total Viewers: 4.4 million
Why: "Marry Me" is pretty funny, but got lousy numbers. NBC just can't buy a comedy hit, and it probably won't buy a Season 2 of this Ken Marino-Casey Wilson comedy.

Show: "American Odyssey"
Network: NBC
Demo Rating: 1.1
Total Viewers: 5.4 million
Why: It is truly too early to make a call on "American Odyssey," but the small sample size we have spells bad news for the show, which debuted on Easter after "A.D." Unfortunately, it didn't sniff "A.D.'s" numbers.

Show: "About a Boy"
Network: NBC
Demo Rating: 1.4
Total Viewers: 4.6 million
Why: This Boy isn't doing so hot, and with Jason Katims' other NBC Thursday night show "Parenthood" over and done with, one could certainly make a case to cut this dead weight. TheWrap handicaps this one at just a 25-percent chance of renewal, making it by definition twice as bad as the "coin-flip" category.
