Personally I thought it was awesome. I was crying half the time but awesome none the less.
First I'll start with the ending. I don't think Dean is actually in hell. I think its purgatory. The chains signify that he is. You always here of being "stuck" in purgatory. I dunno lol it makes sense to me. And I think Sam is going to go all gung ho and be the powerful person we all know he can be.
How long do you think it'll be before he can climb his way out or how long before Sam can save him and how will all that affect their relationship. I'm not sure how long it'll be but I don't think that they will be the same. Heck it might not even be the same Dean or better yet Sam might be different once he taps into his power.
Well I just want to hear some other opinions.
Let me know what you guys think!
