Shia LaBeouf is holding out hope for the third "Transformers" movie -- even though he admits the second one was a letdown.
According to LaBeouf, the next installment restores the human element that was missing from "Transformers: Revenge of the Fallen."
LaBeouf said, "When I saw the second movie, I wasn't impressed with what we did. There were some really wild stunts in it, but the heart was gone."
