Clearly this film has massive, massive issues. The only reason it gets a reasonably OK rating is from my love of the original Tron and how much fun I had with it in the theater. It squanders so much potential (all due to the screenplay), but I still enjoy it - especially the first 50 minutes.
I normally hate found footage movies, but I thought that this was excellent. Wonderful pacing and progression, well acted, great characters, and well done effects - I was especially impressed with the flying. The third act is so balls to the wall awesome that I left the theater on quite a high - so I might be overlooking some of the movie's weaknesses. Either way, highly recommend!
