After I watched the movie, I had a terrible headache. Later I found out it was because I focused on the blur parts of the screen. When I see a 3d movie, I want to see everything in 3d so I watch every part of the screen. But that's not allowed, because you're only allowed to see just the sharp part of the scene. And in Avatar that's just a small part of the screen. So there you have a planet what should be mind blowing, but it's only head blowing. I still don't know how Pandora looks like. After 1,5 hour I got used to the 3d a bit so I could see the last 1,5 hour better, but then the overviews of the planet where already done. What was left was a very one dimensional story. But I already expected that.

Conclusion: Before you're going to see a 3d-movie first learn how to watch a 3d movie. Otherwise it's going to be a painful evening.
