Yes; Life of Pi is one of the most beautiful 3D movies I've seen, and a good story (based on an award winning book). I'm having trouble convincing people to go see it though...
I'm in the same boat (pun intended). Hardly any of my friends have seen it and I'm considering it in my list of top 10 movies of all time! It was moving, although I'm not sure if I would have enjoyed it as much if I saw it in 2D...
