I went to see Tron Legacy the other week, and to be honest, I didn’t think it was a very good movie. But the company was great, and there is something about that darkened room and the other world you enter. (Hat tip to Linda Holmes.)
If you happen to understand Portuguese, the beginning of this lovely movie Lisbela e o Prisionero captures that same feeling.

A great feeling one would say.
