Seeing how little people appreciate the TOS makes me want to cry.
Oh, I liked the original series, too, but it looks so dated now, doesn't it? Still, they had some great episodes. Mirror, Mirror, The Day Before Yesterday, Amok Time, and The City on the Edge of Forever were some of my favorite ones. Got to give them credit for getting the whole thing started. If you've never read it, look for The Making of Star Trek, which was written mid-way through the 3rd season of TOS. Very interesting and enjoyable to read.
