Pretty good episode, only thing that bothered me was the whole hype over Castiel being the new God and its over with already in the 1st episode. I was looking forward to seeing how that would have played out throughout the whole season. But this episode basically should have been included in season 6. It screamed "The Man Who Knew Too Much pt. 2" but I believe that's what they were aiming for. I expected more from Death as well, but his appearance was enjoyable. I imagine Dean and the others were probably scared ****less standing inbetween Castiel and Death. I'm looking forward to the next episode. I'm trying to treat it as the official season opener.
And fantastic title card by the way. Hands down the best one so far.
