hmm... I don't see these going so well... The first Avatar was a good movie, but was more a visual piece than anything else, thats not to say the story or acting was bad far from it, but the biggest part of it was the technology used to create the beautiful landscape and amazing creatures. A second and third wont have quite the same effect because the aw inspired by the first movie wont be the there because it has already been seen. Also the first one ended, and that was it, there were few lose ends and none that were substantial enough to make a squeal let alone 2. These are just being added to capitalize on the massive success of the first, which will have them do well enough, but be nowhere near as good as the first one.
