That complaint is as original as the movie was.
Also let's not pretend Star Wars wasn't equally derivative of many things that came before.
While the derivative thing is true, my take on Avatar after leaving the theater was, in comparing it against SW, was that in SW I always felt pulled in to the story, and actually a part of it, whereas with Avatar, I felt more like an observer. There was absolutely no emotional connection, nothing to connect to. It was a cliched story of bad guy mankind trying to obtain something for evil capitalist reasons and fighting against noble blue critter warriors. Some may find appeal in that, but to me it was just more of the same politically motivated hogwash that Cameron first displayed in Titanic.
I will say that, as with all of Cameron's movies, the visuals and design was fantastic, but lots of movies have that. The Avatar ride at Walt Disney World was far better an experience than the actual movie.
