Rate "Planet Of The Spiders"

In the far future, large mutant spiders rule the planet Metebelis 3, and hold a human colony on the planet, a colony that has technologically regressed since arriving, in the grip of fear.  The queen of the spiders, who likes to go by the name "The Great One," perhaps a reference to her enormous size, is constructing a device to amplify her mental powers by a magnitude of millions using the blue crystals native to the planet.  But the last one she needs to complete the project happens to be in the possession of the Doctor, on Earth.  Soon, the Doctor and Sarah Jane find themselves pursued by the spiders and their human agents, and the chase leads all the way back to Metebelis 3.  And while things don't end well for The Great One, the Doctor pays the cost of defeating her with his own life.

So what did you think of the story that ended the era of the Third Doctor?

Just about gets 4/5. Some great ideas outweigh some dire acting!

I gave this a three. While I can appreciate the Pert's love of all things automotive and fast, this plot was all over the place. And while I can overlook the rather unconvincing spiders (especially the great one), some of the human acting was a bit weak. Not the best send off we've ever seen in for a Doctor.
