It really irks me whenever I hear Avatar called (by critics and others) "the greatest sci-fi epic since Star Wars." It is not! They are nothing alike at all in my view. To me Avatar is not even in the same league (or close to it even). Not that I thought Avatar was bad, just not great by any means and just an ok film (Cameron's previous six films were way way better IMO). Now I totally respect other people's opinions and all but the aforementioned idea is just plain absurd to me.

My two cents.
