Nicely done. Not one of my fave Pertwee episodes but you've managed to capture a wonderful epic quality. Kudos on Aggedor as well. The Beast of Peladon was one of the weak links in this story. You've managed to make him look a bit intimidating!
The story is by no means a classic, but it was a little bit too ambitious for it's budget. I'm glad you noticed that I didn't have Aggedor too prominent - like you said, it's certainly one of the weak links in the show. I like Alpha tho'
