Peter Cullen as Optimus Prime. No other voice actor can be a great Optimus Prime as Peter Cullen. DId you know that he voiced Optimus Prime in the 80's cartoon of the same name? Yeah, i'm serious, look it up. I bet when Peter announced that he would reprise his role, people, that grew up watching Transformers, shitted their pants. Peter Cullen gave us a pretty kick ass Optimus Prime and he does a fantastic job performing the character like he did in the cartoon. I also really loved the action scenes. They were freakin amazing and the people behind the film really took their time to make these scenes look awesome! The CG on the Transformers is very well animated and it didn't look crap at all. I am defintaly going to give an applause to the animators for that. Another thing was the performances of Shia LaBeouf and Megan Fox. While sometimes they can act pretty badly, they were pretty good as their characters.
Now there are some things that i didn't like about the movie. The redesign of the Transformers. They did not resemble their characters at all and i bet that pissed a lot of Transformers fans off. Now, i don't hate the designs, they look pretty badass but i wish they could at least resemble the characters that we all know and love. I'll give a pass for Optimus's redesign because it at least resemble the character a bit. Now, the slow-mo scenes. I thought that some were not very necessary to do, I understand that action and slow mo are pretty cool but sometimes, you just don't need the slow mo to make it awesome.
Overall, Transformers is a movie that isn't perfect and not as good as the 80's cartoon or the 1986 movie, The Transformer the Movie ,but it was still a fun movie to watch.
One of the best action films i have ever seen i mean really
