I only give it a two star because of the image. The environment was very pretty and realistic. However, the plot sucked and some the characters did not really add anything. Also, I felt like the characters personality changed a lot from the first movie. It didn't feel like it was a sequel. Jake was human, and I did not like the way they saw Spider as a pet, that felt out of place. Also, between the end of the first movie and start of the second it felt like they were trying to catch up the viewer and it felt rushed. Also, it felt very unoriginal especially with that serum that they get from the whale like creatures. Also, if technology is so advanced why are they struggling to get rid of the Na'vi and all the other tribes. The fact that its going to take a total of 3 decades from them to finish the enter thing is ridiculous. I think James Cameron is losing his touch.
