The last American virgin

In case you missed the news that "The Bachelor" has never had sex, the three-hour season premiere is here to remind you over and over (and over) again. Former NFLer Colton Underwood keeps cool in the pocket, even as he's introduced to a field that includes a contestant who dresses as a sloth, another who fakes an Aussie accent and a buttinsky who ruthlessly monopolizes his time. Let the games begin.

I want to believe

It's time to give up on another disappointing reboot of "The X Files" and turn the page to "Project Blue Book." This new series, based on the real-life probing of UFOs by Allen Hynek, may not be as ambitious as the never-say-die Fox drama, but it's got a pair of intriguing performances by Aidan Gillen and Michael Malarkey, so deadly serious about their investigations they might be aliens themselves.

Hot for teacher

"Schooled" doesn't have anything new to teach us, but as family comedies go, this spinoff to "The Goldbergs" makes the grade, thanks in large part to former child star AJ Michalka, who returns to her alma mater as a music teacher marching to her own beat. "School of Rock" covered this territory much better, but until Jack Black decides to save the network sitcom, Michalka and company will have to do.
