Maybe it is the worst, but it's still Doctor Who and still much better than most other television shows. With this season, the special effects jump in quality by a large degree. Sylvester McCoy is a great Doctor. Mel... Isn't my favorite. But Ace is fantastic. Wish the writing was better, but the next two seasons after this are much better with Andrew Cartmell taking over.
Still worth it. A great transfer. And at least it goes up from here. :)
