Tron is a great movie! Some scenes were fully epic, the Daft Punk fight scene especially. Michael Sheen is going to be considered one of the great actors of this era, Jeff Bridges already is, Olivia Wilde was great (she's so hot that she could have just stood in one place silently the whole time and I'd still say she was great), Beau Garrett was way hot in the Gem costume.
The effects were awesome, especially Bridges as Clu, if you did not know to look for it you would not be able to see the CGI. Daft punks music fit perfectly.
The story was an amalgam of other stories that was put together seamlessly and worked very well even for someone like myself who has never seen the original movie.
I did not understand some parts of the story like Zeuss and part of the ending, but the rest of the movie was so well done that these issues are probably my fault. Was Zeuss in the original?
I was kind of disappointed about there not being anything after the credits, there was certainly a small part of story left to tell. Maybe they want the possibility of a sequel to be more ambiguous, or maybe the things i thought were left to tell were related to the parts I did not understand.

The "immersion" movie experience was not worth the extra $7, maybe Cinemark's XD really isn't comparable to IMAX, but so far I have to say that I don't understand the draw.
Also, I am still not a fan of 3d, however I think that having to wear my prescription glasses may have something to do with this. There were parts in the beginning where I could see some depth that was kind of cool, but the audience was gasping in awe. Based on the little bit of extra dimension that I can see I do not think the sacrifice in color from the glasses is worth it, a movie like Tron looks like it would be much more enjoyable with the ability to see the contrast between the light and dark colors.
