I've been avoiding major spoilers for the new movie, though I've seen the production shots and looked at the Toyfair info, and I have a serious question... why do the "twins", as people have been calling them, have mutant heads? Are they supposed to be dumb or something, or only half a personality? Are they comedy relief bots? Are they suffering from birth defects? What's going on here? I actually like the other movie face designs well enough. I just can't fathom these heads - they look like they're from entirely different toys and glued on. The bot modes look fine, but the faces are just hideous.
