Cool concepts, but it didn't hold up well.
I think that "Tron" will wind up like "The Matrix"... the visual effects in the original are so far ahead of everything else, that they stand on their own. And then, all of the sequels (or copycats) just don't cut it.
I really enjoyed the sequel, but IMO, the big thing it lacked was the innocence of the first movie. The trend to make everything ‘gritty’ has killed or at least hampered some decent stories. In the sequel it kinda fit the storyline and all, (Can a digital world have ‘grit’?) but the first appealed to me more overall.
Batman? That should have been gritty from the TV version onward. Everything about that story is dark.
