I think Keith Prentice did a wonderful job as Morgan Collins. (Can you hear me Buzz?)
While Morgan wasn't exactly a likable character, he wasn't shall we say, an all-out villian (At least not until toward the end of the show). He certainly wasn't up there with the likes of Nicholas Blair, Count Petofi, or the Trask men.
In fact he was, what I'd think, one of the show's most realistic characters. Say what you will about how awful he was to what he did or tried to do to Bramwell and Catherine (and I'd be the first to agree with you), he was fascinating to watch nevertheless. He didn't start out a villian, but became one, and it was very interesting to watch.
