I dunno. I get making some of the characters different. That doesn't bother me so much. But I think they should have at least made the big two, Megatron and Optimus as close to the original as possible.
I guess from what I read on the subject, the reason they went with Optimus as the bigger truck, is because it made it easier for them to animate the transformation sequence. Something about there just not being enough room for him in the smaller cab? (always worked on the cartoon
) But there's really no reason why it couldn't have been red.
Still, there were some interesting scenes planned. The new 2009 Camaro concept was supposed to be used as one transformer, while the Mustang was supposed to be on the opposite team (one a decepticon, one an autobot) and they were supposed to go head to head. That would have been cool.
However, I think they went too all out on the actual mechanics of the transformation. In the cartoon, their bodies just sort of transformed, but in the trailer for the movie, you see all kinds of servos and hydraulics and bull**** that's too hi-tech looking and really doesn't even feel like the old transformers of any kind.
In fact, there's some weird spider transformer in the trailer IIRC. Outside of the Beast Wars, Beast Machines, and the predicons from the fox transformers cartoon, there were no animal cartoons any of the other series except the insecticons and the dinobots.
It just doesn't _feel_ like the Transformers.
I'll watch it, but I seriously doubt I'll go to the theatre for it.
