I've been a Transformers fan since way back in the 80's I watched all of g1, and the 1986 movie a million times, and this just occurred to me. Grimlock has always hated Optimus Prime. He's never really had a high opinion of Optimus. Why is it in the 1986 movie after Primes death didn't Grimlock attempt to take over the Autobots. It's something he's always wanted to do, and you'd think that would be his chance. I guess it's because Grimlock was really softened for the movie, but even that's a bit weird. It's just a thought, and the movie might have a taken a much different direction too.
