I think they need to cut more here and there and extend more here and there. Add a line of dialog here and there when there was none. Transitioning things a bit better would have help a lot also. I also felt there was a lot of wasted time that could have been better used to add more dialog in other scenes.

I felt the first half of the movie was rather awkward but once things turned away from mars it all started to come together a bit better. Also why was the cat thing there(I don't know how to spell its name and I am not looking it up)? Did I miss the line of dialog about genetic engineering?

I also thought the fights were a bit over the top and crazy for people with no real super powers. That said I did enjoy it.
