Hmm, thought I already replied to this thread, guess not.. Anyway, I had low-ish expectations, so nowhere to go but up. That being said, the premise (and early execution of it) was fun. Reynolds is just fun to watch in anything, and I dig a weird-concept one-off film like this. I REALLY dug the Tron-inspired things that were going on here - and as a former level artist for games, I appreciated a lot of the "game rules" and such and how they were portrayed.
Two things, I found myself REALLY enjoying the first half of the film but really not liking the second half - not sure when I have experienced this to such a degree before, but this film did it. I felt they could have done something a lot more interesting with the resolution instead, but they had to tie it up neatly and satisfyingly, and it was ultimately a kid's film, so there you go.
And that brings me to the second point - yes this IS ultimately a kid-friendly film, and there is absolutely nothing wrong with that. The people in here bellyaching about how garbage it is etc - come on, not every film has to be a masterpiece, sometimes a world can just be fun to hang out in and watch, even if it is flawed. I like that some of the posters were saying they were happy that they would watch it with their kids, there are much more saccharine-sweet drivel you could have to suffer through so this would at least be satisfying for a little different change of pace (and despite the callouts, it isn't "just another Marvel film" which is fine too, but people gotta be starting to get a little burned out on those). Anyway just my $0.02.
