On a side note: I watched this movie on a streaming site... (i.e., I watched it in poor quality).
That was a bad choice.
The plot, storyline, and dialogue is kind of weak. The visuals certainly are not. Watch this in high-res quality, and think of it as an over-budgeted Daft Punk music video instead of a movie, and you'll have a great time watching it.
As far as cyberpunk in media that dare actually include cyberspace aspects (so for example, not Blade Runner), I think it stacks up pretty well. The Matrix 'cheats' by explicitly declaring that their cyberspace was built to seem real, and Johnny Mnemonic, rather bluntly, falls on it's face when trying to pull it off (I do love that movie though).

It is amusing though that pretty much everyone agrees that both movies have deep flaws. The disagreement seems to arise in whether the things the movies do uniquely correctly (or at least differently) make up for it. Not exactly a ringing endorsement no matter how you slice it.
Check out the Disney cartoon Tron Uprising -- it has a similar but different visual style, a dash of Aeon Flux, and gorgoeus sound deisgn that builds directly off the Daft Punk soundtrack. The story is okay too especially as it gets much darker towards the end of the season.
The show is 5 seconds from being cancelled but the first episode is still free on youtube: http://www.youtube.com/watch?v=hjbwVzJR8w4
Rest on iTunes/Amazon/Xbox/whatever
But... This soundtrack, fits so perfect, and i still listen often to it while chilling or coding. So. Awesome.
