Ugh, I know what you mean. :\ I've been spending an increasing amount of time shielding my eyes and telling my friend "tell me when it's over!" while watching lately. (...then again, this applies to the non-graphic scenes as well *snerk*)

While I don't think Supernatural was really misogynistic in the beginning* (the first two seasons, anyway), I do think it's been getting a lot worse. I won't go into all my thoughts on that, since they go into the realm of "stuff that will cause wank", but yeah.

* my joke about being able to tell who was going to live or die based on hair color notwithstanding.
