1. I've done this with at least two fandoms, because I couldn't be arsed to watch 20 or 60 episodes of a tv show I didn't had much interest in just to get the background of a fic a friend was raving on about.

However, there came the time - and it came pretty quickly - where I sat down and watched those episodes. I never regretted it with either show, one of which was Heroes. Words, by the way, do not do Mohinder's prettiness' justice.
