The only saving grace (and the only reason this ep didn't get a 2) was pretty much due to the last five minutes in which we learned why the boys haven't been running into a whole lot of demons lately.
Turns out Crowley was a wee bit insulted by Dick and kinda really wants the boys to take those smug leviathans out of the game. (I can completely understand... after all, don't we all choose the devil we know over the one we don't?).
Other than that... I will say at least Dean tried to be supportive. I'm a little surprised he didn't try investigating a little harder though. It was just really poorly written.
As always Jensen and Jared, special love to you both and apologies to you both on behalf of writers everywhere.
