I would have loved if we saw Optimus experience PTSD, like not explain, but show it. Because the movies don't do that when somebody said, Prime acts that way because he has PTSD, he's hurting...i don't see it. all i see is someone killing left and right. Who I'm i kidding, it's Bay. Maybe in the new movies, because i would like to see everything that happens stick with Prime, show that it's haunting him, and just..scared of ever losing himself.
