Why So Long?

I'm not sure why all the critics are raving about The Dark Knight. It's good, but not THAT good. Besides that, with a running time of around 2:30, it felt long (and a little like two movies). And considering we spent $32 for parking (double what we anticipated), $24 for two tickets, $5 for movie candy and just under $4 for one soda, I can barely say it was worth the price of admisstion.
