VFX: The original Tron still looks pretty good for its age. With the improvements in CG, this really does look like fantastic. This whole damn movie looks fantastic.
Fights: Really well-choreographed fight scenes. This and Scott Pilgrim had some of the best fight scenes from an American movie that I'd seen this entire year.
Soundtrack: Daft Punk. They did the whole score, but only about half the tracks really sound like Daft Punk songs. That's one of the gripes right there. Half the tracks are awesome techo songs and the rest are kind of bland.
Cast: Garret Hedlund plays Sam Flynn, our protagonist. He certainly did a good job, but he was kind of overshadowed by Jeff Bridges and Olivia Wilde. I was surprised with Wilde's performance. She was just adorable, which I was expecting an "action girl" type. And Jeff Bridges didn't reprise his role of Kevin Flynn, he was the Dude. The Dude in a damn Jedi robe. Too cool. Cillian Murphy's cameo was pretty surprising and welcome. Bruce Boxleitner is always good too. Always kind of wondered why he never had a bigger career, he's actually a really good actor.
Reverence: There were a lot of scenes that were shot in the same style as one's from the original TRON. Like when Sam broke into EMCOM Tower through the "big door", the escape from the Game Grid, and the ending itself to name a few.
Syd Mead: He contributed a new lightcycle design that was briefly used in the film. I like him so much he gets his own positive category. His art and designs are just so pretty.
Tron: Like in the last film, Tron's not really the main character. At best, he's a plot device in this one. He doesn't really have much of a presence. I mean, yes he's in it. But I was kind of hoping he would be swayed back to the side of good before the last five minutes.
Setup: It was sort of obvious that someone was hoping this would lead to a Tron 3. Cillian Murphy's cameo, Tron's fate, the ending in general, it was kind of obvious that more is hopefully coming. These were just loose ends.
Blackness: The fact that everything was black except for those white/red lines on things made things a little disorienting when things started moving fast. Maybe it was just the 3D or the IMAX screen, I don't know. It wasn't bad, it was just slightly disorienting.
At the end of the day, this movie's pretty accessible for folks who haven't seen the original Tron, but it's definitely made for the fans of the original.
