Why don’t film makers come up with a new story line? Not only is it the same story but with less told in more time, Cameron didn’t even get a new villain. A pathetic homage is played to Titanic when monkey-boy tells the girl to hang on to him when the ship sinks and of course she can’t. At the end of 3 hours we get Sully deciding he should now fight for Pandora so we get to the end of the movie and now get to wait for the sequel… Avatar 3.
Great CGI of underwater world but better off just keeping Avatar 1 in your movie collection as it is a complete story with a beginning, middle and end. You don’t really need to see this movie… watch the first one then go to a good aquarium (SeaWorld or Sea life etc) for great underwater scenes!!!
