It seems the producers really intended for the Autobots to be closer to humans in look, while the Decepticons are more alien in faces and bodies. I *am* surprised Hasbro managed to translate the movie designs to toys so well for what we've seen so far. Needless to say, Optimus Prime and Bumblebee are already 'must-buys'.
Starscream here seems to have claws for fingers between those guns but it's really the head I don't like: it doesn't look good at all, even in an alien way. The body in general isn't bad, and I actually like the more animalistic legs as they remind me of Gargoyles, one of my favourite shows.
I do regret that the Decepticon so far have so alien faces, but it reinforces my prediction that most Decepticons in the movie are going to be faceless cannon fodder.
