“Penguins,” the latest documentary from the folks at Disneynature, consists of 76 minutes of penguins waddling adorably across Antarctica. In IMAX. This is basically all you need to know. It’s got the cutesy anthropomorphizing that marks so many films in the series and makes them extra kid-friendly, but this time it’s far more enjoyable with Ed Helms lending his everyman voice to a bumbling Adelie penguin known as Steve. Don’t even bother trying to resist. My review, at RogerEbert.com.
