Although I'm expecting a lot more from this season,but so far I haven't seen an episode which is worth giving a 10 stars. I wish that they will stop ruining Castiel's image by making him The vessel of Lucifer, really Castiel doesn't fit to be the bad guy. Misha is a good actor but since he started as Castiel with that peculiar character , adorable and sometimes funny , being Lucifer's vessel is one of the worst idea in this season , and you can see how Mishia is struggling to mimic the character of Lucifer...it's not so bad though...I think he's a whole lot better being Castiel.Well at least in my opinion.
On the other hand, it's about time that Crowley got out of his cage after being Lucifer's dog.For the first time I felt bad for him, but I always loge his character no matter how bad he is.
The story overall is simple, because once again we're back to demons making business.I thought demon days are over since the Darkness came in.
They should be thinking of bringing back Bobby Since he's one of the character with strong personality in Supernatural.
