Query: The worst Doctor Who episode ever made.

Although I love Doctor Who, I have to admit that this was the worst Doctor Who episode I have seen. The quality of the footage is excellent, however the original plot and filming is terrible. For instance, in one part you can see the shadow of Ian Chesterton fall across the "distant" mountain range. The plot is very slow moving, involving people in bug costumes standing around waving their hands. There are some good Doctor #1 episodes out there. This isn't one of them.
