Funny, but the animation doesn't add much.
The dialogue was funny, but there doesn't seem to be any humor added with the animation. The characters expressions stay the same and therefore don't reflect their reactions. A raised eyebrow or something else done to change them from their static facial expressions would have brought a little more humor into the mix for me.
There's nothing wrong with subtlety either, but subtlety can still be expressed in some different facial reactions.
you should make a preloader
You should have made some kind of joke from Batmans punch line "Im the Batman!" :P
But cool video, nice :D
