First off, it's been a real kick watching these old shows again!! As for this particular episode, I thought it worked well enough. It moved along smoothly and I was buying everything that happened, no problem. I'd particularly like to applaud the ingenuity of the guy whose job it was to create the alien creature on this one. He could've easily created a suit for a single person to get inside of...but instead he came up with the brilliant idea of creating a 2 person suit!!! I'm sure when I watched this years ago as a kid, that thing scared the crap out of me!!
