I was waiting and waiting for a happy ending...
But it didn't come... It all went by so quickly, I thought it had another minute or two left, but it ended. Excellent change of pace! You guys are making things less predictable now, and that's always good. I swear, if this went on for 10 or 15 minutes and kept the same theme, it probably would've brought a tear to my eye.
Awesome movie and all, but it did put me into a sort of depressed mood. The 5th installment can't come soon enough.
