Leaving the nest

The daughters from "The Fosters" may have learned a few lessons from their adoptive parents, but not enough to keep them out of "Good Trouble." Maia Mitchell and Cierra Ramirez return in this well-intentioned spinoff that finds them fending for themselves in the rattrap commune located in a part of Los Angeles the Kardashians have never stepped foot in. The producers, which include the show's stars and Jennifer Lopez, deserve credit for packing the soap with diversity.

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 Aiden Gillen and Michael Malarkey.

Choppy waters

"USS Indianapolis: The Final Chapter" offers a well-taught course on the history of the doomed ship that was sunk by a Japanese sub shortly after delivering the atomic bomb that would destroy Hiroshima.
