Looks kinda like a kids' movie

Well, it's no different from the original in that respect, except maybe less ground breaking as CGI is all pervasive today. TRON Legacy managed to overwhelm the senses in IMAX 3D down to the end credits. Just as brainless as it was in 1982 and just as fun. There were young people coming out of the screening taking about "that movie has many problems". But it's all about art. The Art of TRON back in 1982 was avant-garde, towering primitives of neon-clad architecture. The aesthetics of TRON Legacy sill please and the phrase "Tron-esque" will continue to be used as a result.

If you're looking for something to make you think, it's limited to the use of colour and space. The movie is a highly technical exercise probably only of interest to computer graphics engineers. Digital actors are convincing until they try to talk. Once they lick that problem I shudder at what might be possible, or the legal implications of resurrecting Humphrey Bogart to star in new films.

Perhaps too much pandering to the audience with repeat dialogue from the 1982 movie. And lots a tight ass shots. Well, that was kind of OK really. Characters we didn't really care too much about.

To sum it up in a phrase, TRON Legacy is "an architectural piece". I loved it. TRON 2.0 the video game had better story and dialogue though.

To be fair, the movie never billed itself as being any sort of "high brow" sci-fi like Blade Runner or 2001. For anyone who remembers the original Tron, the dialogue and acting wasn't exactly Oscar worthy.

How did TL bill itself (if it did at all)?

...and not a grid bug in sight.
