SPN episode poll

I'm always curious how people rank the episodes, so I thought I'd post polls as the season progresses, just to see which eps are the overall favourites and least favourites, and how quickly it changes once there are more eps to choose from. Please feel free to tell me in the comments why you picked what you did. I'd really like to know. :)

ETA: Just to be clear, the third option in the poll is for your LEAST favourite. Sorry for the confusion!

[Poll #1474948]

( My choices are... (spoilers abound) )

So, that's me. What about you?

(I'm leaving this public, so feel free to pimp if you like.)
