Honestly, I'm not a fan of the original, but then again, who is beyond nostalgic value?
But I don't think that should stop them. It really looks like they've done an awesome job to fully realize what they probably set out to do the first time but couldn't. I know several people who already have opening night IMAX tickets for this.
They had TRON 2.0 killer app, not too long ago and game that was pretty good. I'm a huge fan of the original and hope to be pleasantly surprised by this one.
