I saw JJ Abrams' Super 8 today. It's quite fun -- has some problems toward the end, but it built up so much good will for most of its running time that they don't matter so much to me. Maybe they'll become more glaring upon future viewings?
Either way, this movie has a ton of great stuff going for it. Any scene involving the main character, Joe, and the girl he likes, Alice, is pure magic. One scene in particular involving Alice trying to impress Joe with her zombie impression is probably my favorite scene in the whole movie and my favorite scene of the year so far.
I could have watched a whole movie of these kids just making a movie without anything weird happening.
