The winter movie doldrums are over and there are two terrific movies opening this week.  If you haven’t heard about the best-selling “Divergent” series of books, think “Hunger Games” (dystopian YA trilogy with a plucky female heroine) and read this summary from Hollywood.com to get you up to speed.  And the Muppets need no introduction, so I’ll just say that this film includes not just Tina Fey and Ricky Gervais but an evil second Kermit.  Pass the popcorn.
