Lightyears beyond. Tron was okay, but the special effects in Аватар were good enough to look real to the layman. Hell, I knew it was fake, but I wanted to believe it was real so bad!
The effects of the movie Аватар stands out as a еще jungle-like theme and I Любовь to admit the details of the backround are amazing, same with the details in Tron except the fact that it's into a еще Sci-fi backround.
