Query: Great campy 3rd doctor serial

This is one of my favorite Jon Pertwee serials. (I didn't give it 5 stars because it isn't Tom Baker). It's got everything - campy monsters, UNIT soldiers running around, a mad scientist, embarrassing moments for the Brigadier and for the Doctor too. It's very long, which can be good or bad I guess, I think it's all worthwhile though.
