S:What'd you got?

D:Dragon penis.

S:....What?

I agree with the grade.  A meh filler episode.

Horrible show, horrible acting (Padalecki and Ackles, I never know which one of you is worse.  "Model Face"
"Ackles or "Constantly Surprised" Padalecki.) 

This series should have ended at Season Five.  Awful, awful, awful ever since. 

Let someone else save the world from now on.

 I didn't like the ending but I thought it was an okay episode.  Making sure it was an eagle picking at roadkill Prometheus was a nice bit of attention to detail.

By this time, I'm thinking any god with at least two functioning brain cells would not want to be on the same continent as the Winchester boys, much less in the same building.  I mean, they've been the cause of death, directly or indirectly, for, what?  At least a dozen gods?  Throw in being involved in the deaths of two archangels, the king of the Leviathans, most of the high ranking demons, the Whore of Babylon, and the mother of all monsters, plus the incapacitaion of another god, a number of Leviathans, a Knight of Hell, three of the Four Horsemen of the Apocalypse, and two more archangels, and I'm thinking Sam and Dean hold the title for being the two most dangerous beings on Earth.

I agree with the C grade but not to say it wasn't a bad episode.  I enjoyed it as well.  The ending left me a bit off.  Not sure what kind of payoff I was looking for but overall enjoyed it for what it was.
