I think Tron Legacy is a very nice film, even if the story is very basic (but it still worked for me) and more a vehicle to get through the most stunning visual effects world that I've seen (3D). I also noticed lots of little details / nods to the old Tron, which was really nice and funny to spot them. I think I even found a "bit" in there.
The knew that the Soundtrack was good after having it on my playlist for a few weeks already, but I didn't expect it to be that awesome with movie together.
Btw: Kevin Flynn has transformed into the dude man...
