Ooh, if you watch The Outer Limits look for Demon with a Glass Hand, it’s a classic. There was actually talk of bringing the character into the Babylon 5 universe, but I guess they couldn’t work it out.
Nothing in the Dark with a very young Robert Redford is one of my favorites.
I thought that episode right before I read your post. This is definitely one of my favorite ones. Of course, there are the famous episodes such as “Terror at 20000 Feet” and “The Eye of the Beholder” (This is the plastic surgery one) . “A Quality of Mercy” is good. Plus, it has Dean Stockwell in it. Dean Stockwell always makes things better.
