There's a lot of stuff I'll put up with, but the Enterprise ep "Precious Cargo" is just ridiculous. Okay, I'm in the middle of it right now, so I can't really comment, but it starts with Trip playing a harmonica. A freaking harmonica. I don't like harmonicas. Never have - except the plastic ones from when I was five.
Side note: What is it with Kriosians and stasis?
