Nah, his bow shouldn't flop around when he 'opens' it, it should be more mechanical in nature, it really does look like two dildos attached to a metal rod.
Not all what I expected or hoped to see, should have been closer to the bow he has in the animated series, it's not like they need to stick to the more realist look, the movie has a God in it and a giant green monster and a man who was frozen for 50 odd years...
Hell, I'll take it further. I'll bet a one month ban that it doesn't break the $200m barrier in the US. That's how confident I am that it's not going to happen.
