I found it really boring
it was very predictable mostly and lots of pointless wondering of Cas, I get thet they wanted to show him struggling with the human side, food, shelter, money, sex, peeing and gas
but seriously it was aimless to me at some point why dont he just call Dean or get to the bunker which is another confusion, he die, comes back, get the the bunker and now has to leave?
too much disconnect for me in this ep and seeing Sam turned on and off like a light switch was not fun to watch.
