Are ''Up,'' ''Mamma Mia'' and ''Star Trek'' worth your buck?

Casting a vote for the classic Star Trek crew or The Next Generation has always been the sci-fi equivalent of Sophie’s choice. Now you can choose between two dueling DVD boxed sets — Star Trek: Original Motion Picture Collection (featuring six Shatner films) and Star Trek: The Next Generation Motion Picture Collection (four Patrick Stewart movies). Our Pick Next Gen. (Or you could just buy both…if you want to risk being called ”coward” in Klingon.)

Ten movies into their miracle run and Pixar still hasn’t cranked out a clunker. The studio’s latest, 2009’s Up, is a gloriously touching tale about a crotchety old widower who defiantly takes flight (along with a chubby, chatty little castaway) by tethering balloons to his rickety old house. The whole movie soars, as do the DVD extras. Our favorite: Dug’s Special Mission, an animated short that shows us how the film’s lovably dumb mutt met his human pals. In four short minutes, Pixar proves the old saying that good things come in small packages.

Mamma Mia! The Movie — The Gimme! Gimme! Gimme! More Gift Set
Personally, we don’t know anyone who’s rabid about the movie version of Mamma Mia! Like it? Sure. But enough to cough up $25.99 for The Gimme! Gimme! Gimme! More Gift Set? Even if you know every last lyric to ”Dancing Queen” and ”SOS,” we’re guessing you already own the movie and the CD that are included here. So what’s left? A 32-page collectible book, that’s what. Do your groaning shelves a favor and give this one a pass.
