The second half of Season 6 was good but I didn't really get Samuel and Dean's insertion back into hunting felt a bit forced but I liked when we were able to visit home from time to time.
Ok, so Crowley's dead. Sam has his soul back. What now? It really seems like S6 has no clear direction. I still enjoy it though, so I'm going to keep watching. They'd better get S7 on Netflix pronto!
