____ em both.
They're similar in that they generated undeserved hype. What both films DO deserve however are awards for the most over rated films of the decade. Though to it's credit, Avatar had it years before it's release where as someone just woke up a week before Inception premiered and proclaimed it to be the "best movie evar!" and then as the story goes, people soon followed suit.
But if you'll noticed, it's died down alot. Inception was in the spot light for a little under a month to the general public. Not very long in my opinion and rightfully so. I'm sure it will pick up a little bit with home entertainment releases and then the inevitable "OSCAH NODS" but it'll soon be forgotten buried under the weight of movies before and after it. Speaking of oscars I'm sure there are a few individuals here that think it's more than deserving of a few nominations and/or wins.
I've got to say, I may not like the film but it deserves at least a nomination for cinematography (Wally Pfister). Other categories though? No, no.
Did I think Inception was okay? Yeah. Mind blowing, thought provoking awesomeness? Hell. No.
