Wrong. It's like being disappointed because you were charged 25% extra for color and then the whole movie wasn't in it.
I saw it last night in IMAX 3D. I'm gonna give it a B-.
The effects are real cool. I really can't over-stress how cool the light cycle and plane sequences are. But they are only 5% of the whole movie.
The digitizing of Bridges' 1980's face into the new movie is believable as a human representation... but it doesn't look like him, really. At least not exactly.
The soundtrack (which I have had for a few weeks) works better in the movie than on album, but there are a couple of tracks in the movie left off the soundtrack, which sucks because they are more towards the typical Daft Punk sound.
In hindsight, I think if you really liked the original, you will be disappointed by this new movie in many ways. I'd compare it to Star Wars in the way the prequels had none of the "charm" or "soul" of the original, even though they were vastly superior technologically.
My biggest beef is the story line. There's a few huge-ass gaps in plausibility, but my main issue is that there is almost no implied connection between the two worlds. In Tron, there were analogies between outside/inside the grid, and there were cues about users affecting programs and vice versa. Here in the new movie, it's either laid out matter-of-factly, with no explanation - or ignored completely. It's a bit hard to explain, but it's almost like the similarities between the movies are only the light cycles, data disks, and Jeff Bridges.
Meh. It's a very slick film, but the technology is not as patently gee-whiz obvious as in, say, Avatar. Tron Legacy is too geeky to be a smash blockbuster, and too imperfect to survive only on the nostalgia crowd draw. Not sure where it fits into the grand scheme.
