I loved Tron: Legacy, and have seen it twice already. It's incredibly fun and beautiful while at the same time being deep and intelligent. It was crafted with true love for the original, and has an amazing tone of seriousness and some fascinating ideas. And the actors are all brilliant! A must see!
I came for the spectacle (and mainly for the Tron trailer) but was pleasantly surprised at how engaging the actual movie was. (Except for one brief cringe-inducing scene towards the end so bizarre that it's almost like dadaist performance art humor in retrospect).
A great movie that was interesting all the way through, and sometimes hard to watch because of how horrifying and upsetting the story got (but not in a pointless way).
I thought this movie was great fun. After I saw it, I couldn't understand all the bad reviews I'd seen from reviewers and fannish websites. It was enjoyable and cool and the only minor part that I didn't understand was easily explained after the show by a line I must've missed. I say go!
