Peter Davison was not nearly a great doctor who. In my opinion, he was the third worst, (Colin Baker being absolutely awful). His portrayal of Doctor Who was mostly due to inferior writing, and not of this fine actor's true talent. He was great in "All things great and small," but as Doctor Who just didn't pass muster. His reign was the beginning of the end for Doctor Who, and the series never recovered from the idiocy of the Eighties.
