Well, the hype certainly has not died on imdb.
Inception is still #8 of all time on their top 250. TDK is #10.
I'm sure they will both move lower over time, but can't see them dropping out of the top 20 on imdb at least.
And I have yet to come across a more consistent movie ranking than imdb.
Of course you can argue such movies are voted up by fanboys, of which there are plenty for Nolan and Dicaprio, but still.
Anyway, not sure where I was going with that.. i guess point is, Inception was a GREAT movie to me personally, and it seems to many many others as well.
