Every forum that has a topic about it think it's gonna stink Shocked
That's not surprising, and frankly I can't blame people for being so jaded. Hollywood spends millions and millions of dollars on a movie and ends up producing crap. However, there's also the people who just like complaining. It's like they've become so used to seeing crap that they actually WANT crap.
I actually want this movie to be good, and personally I think the concept (no offense to anyone) is so basic it's INCREDIBLY hard to f*ck up.
Hollywood will find a way though.
The most realistic prediction I can give is that this will be a mediocre to good (not great) movie with some decent special effects. People will complain about the redesign of the TRON suits or the lightcycles. They might also complain about the improper use of gaming technology and terminology in some scenes, and will most likely be appalled at the blatant advertising of some games, "a 2 hour videogame commerical".
That's just my prediction though.
