It's really interesting seeing what people's tastes are..among the usual suspects, there are also episodes I'd never expect people to dislike, as they're generally liked.
The other thing that is interesting, to me anyway, is how some episodes bring about such polarized if I'm using that term correctly) opinions, like The Royale (I'm sure it's not the only one, but it's the one I noticed). Some refuse to watch it, and others come and defend it saying they love it! But I guess that's part of the fun!
