The show doesn't really make me sad anymore. I haven't enjoyed it since s3 honestly, but I can get by more or less because the show is still somewhat entertaining and interesting in a background sort of way. To me it's the fandom that is intolerable at times because they are just so centric and static on one character and seem to only watch to preen and build one character up while tearing down another. They don't even bother to try to see things towards the other characters they interact with. As far as I am concerned s4 was the worst thing that ever happened to this fandom as it brutally divided fans and as such it hasn't been the same since. I know what you mean about staying together. I honestly try to love them equally, but there are dean!girls who make it so difficult in wanting to like both of them with their hatred for Sam which is often irrational. I love Sam and I love Dean and most of all I love their relationship more then either one of them individually. It's why I continue to watch.
