It just felt darned empty. I felt like I was reading an interesting Batman graphic novel that was highly acclaimed but sorely lacking in a well defined story arc, and just got too convoluted for its own good. Add in the overlong run time, messy editing, weird color scheme and "HOCKEY PADS" and I guess that about sums it up for me. It's not a bad film, just not the great movie everyone claims it to be.
I'm going to revisit it tonight anyway and see what I think all this time later. And I still haven't seen Inception, which of course will get me ignored by some people...
