Sorry to break your fascinating conversation
but I actually went to the cinema (only one is still playing it) today to see it...
I've heard very mixed opinions so I didn't know what to expect, and putting it short - I really liked it. It's definitely impressive in terms of how it looks (the whole world is indeed incredibly beautiful, despite being dangerous), and I don't think I need to elaborate much here, in fact I guess I would fail miserably if I tried to. However, I also really liked the storyline. Sure, it's not the most original or revolutionary idea ever, but the way it's in Avatar is just great - I also really liked the whole idea of the main character, for some reason I could immediately understand his actions.
There were some parts which definitely felt naive to me, but well, no matter. It was definitely a great experience and I don't regret the over two hours spent watching it at all.
[And I hope I won't start a tornado, but I can't understand people claiming Avatar is stupid and flat, at the same time worshipping Dark Knight for being deep and philosophical...]
