I agree, I think the story will be the weakest part. Visuals look amazing, soundtrack will be awesome, but I don't like how they're just dropping the Sam Flynn/Quorra storyline.

Also, I know this is a nit-pick not worth worrying about but I find it weird having Recognizers (the two-legged floating transports) in the real world. In The Grid, things can float because it's all inside a computer anyway, gravity is just a function of programming. But you can't just teleport a Recognizer into the real world and have it float. It's not like the people within The Grid invented anti-grav technology or something, it's just a program. For some reason I'm fine with having lightcycles in the real world and yet having Recognizers just breaks my suspension of disbelief. And I'm sure the movie won't even try explaining things like that; it'll just be a dumb, fun, action movie.
