I don't know what to think.
I've enjoyed Transformers 1 and 2, although I didn't like everything about them.
Well, at least he isn't outright directing TMNT, just producing it, so that's some consolation.
Still, I was an active message board member of the official Transformers movie site when they were making Transformers 1. It was pretty frustrating seeing designs that didn't look at least somewhat recognizable and the writers questioning EVERY little thing from the mythos. I know I'm going to see the same things with a MOTU movie if it happens.
