Big Bang Theory
The best thing I saw was not a movie, but finally getting a change to check out some episodes of this TV series. It's awesome (as much as I like musicals, this might grab top spot from Glee in my limited TV-watching time). Like many of the awesome series work on TV, this is very much writing-driven, with the actors gleefully each pushing their characters to the extreme of their role. So fun to watch, very light although the characters stay real enough to keep you coming back.
Scott Pilgrim vs. The World
As all friends who've seen it reported, this is a really fun movie. The videogame tropes come fast and furious and despite our hero's relatively lackadaisical approach to life it's a fun ride to watch. The visuals are awesome, completely having fun with the situation (as does the movie in general -- you're clearly meant to believe in the emotional journey, not the literal events).
So, I'm not a huge fan of this franchise but this was a totally entertaining caper movie. In this case, calling up the testosterone warhorses (Vin Diesel and Dwayne Johnson) and putting them in roles suited to them lets them just have fun with their toys (many of which explode very satisfactorily). A host of fun ensemble members round out the banter. Opening prison break sequence is awesome, as is the train heist sequence. I kinda wish I had seen it in the theater, this is a loud summer popcorn movie.
Kung Fu Panda 2
It had a subtitle, but it doesn't really matter: the plots are going to be pretty interchangeable in this series from now on. This is an OK sequel (seeing on a plane was optimal), the additions to the character list mean that no character really has time for actual character arcs. They're still having fun with the concept though (Michelle Yeoh joins as a soothsaying goat with a tendency to eat whatever paper is in front of her), and both the opening and ending credits are beautifully designed (someone finally figured out that scrolling text is a bad idea!).
