Peter Cullen can make me overlook a lot of flaws in this movie (and there are a lot). I was a fan of the original show and they handled Optimus Prime's characterization exactly right: brave, wise, and philosophical. Cullen's voice adds a lot of authority to his character. I also found Bumblebee and Sam and his family likable.

Pity the rest of the movie that surrounds them is so crass and aimed at the lowest common denominator. I still enjoyed it, but I think a much better Transformers movie could be made from this material.
