No, I'd say you missed my point completely. Which was, that it's just like any other popcorn flick, but it actually has some sort of moral compass/social conscience. It's not completely brain dead entertainment like those race car heist / robot movies.
Avatar may not be "relevant" in pop culture as Fast/Furious or Transformers, but it also hasn't had multiple sequels on a regular basis.
You can choose to compare it to Dances with Wolves or whatever, but that doesn't mean it has any less of a social message. It's not brain bending Sci-Fi, but it still has a brain.
