It goes back two three Doctors before Tom Baker became the Dr I think!!

There was an episode that scared the shit out of me when I was about 6 where some creature had its blue hand chopped off but it still crawled around the floor!!
I'm amazed this came back and became popular with a new generation..

I started with season three (with recomondations from other Netflix users). Man its great, hope you guys check it out, give it a few episodes!
