It's no "Twilight Zone", but very, very good all the same. Very cool to see such a young Leonard Nimoy, and this was a nice variation on the old Frankenstein story.
Stupid Observations:
The way people pronounced the word "row-butt" back then is funny. It's also amusing that in the beginning of the show, one guy actually thinks it's a good idea to go after a 300 pound robot with a pitchfork.
Spoiler: The writers were really ahead of their time. The way Adam is taught in this episode is exactly the way many robotics engineers and scientists teach AI robots today - building upon layers of learning, as if they were babies.
