@contrex,
I haven't seen it because it's not my cup of tea- I generally don't like science fiction as subject matter and am not really interested in special effects.
Having said that, when my son brings a movie home that entails all of that and I have nothing else to do, I'll watch it and at times, when there's been an interesting story line or characters, I've surprised myself by liking it.
Does Avatar have a good story to tell?
