Post-TDK Depression 

After watching The Dark Knight, you settle into a depression because of the realization that no movie will ever be as good again.

Man, I was watching Tropic Thunder the other day and it was kinda funny, but The Dark Knight was a million times better. I'm just gonna go watch it on IMAX so I can beat this Post-TDK Depression.
