1) Joe Tormolen is an idiot. From the crappy environment suits to him taking his glove off and then not saying anything afterward (apparently thinking decon would take care of
it) was just ridiculous.
Every person I've ever watched this show with (including my 6 year old) thinks Tormolen is an idiot! It takes the gloss a little off this othrwise classic episode. I suppose, yeah, he could have just assumed de-contamination could have fixed things.
One thing I really enjoy about these early TOS episodes is the greater budget allowed for us to spend a bit of time with crew members other than Kirk, Spock and Bones. I would have liked to keep bumping into the likes of Janice, Riley, DeSalle, Kelowitz, etc in seasons two and three.
As for the TNG remake, I loved it as well, and thought it was one of the more entertaining early episodes. I can see how it would have disappointed a lot of content-starved Trekkers in 1987, though - "episode 2 and they're doing remakes already".
