Supernatural season finale.?

What did you guys think of the ending and over all season? I liked the season except all the fillers. They portrayed Lucifer perfectly. You expect the devil to be the most evil thing ever, but he's still an angel and he's very honest and still feels for his family. But he's also insane and wants to kill everyone. As for the finale, the ending was good, but I disappointed. they should have made it a two part thing, or two hour episode. They really rushed everything. You expect a big showdown between Lucifer and Michael. They really should have worked harder. I also think it would have been so cool if Castiel turned out to be God. What are your thoughts on Chuck at the end? Did he ascend to heaven? Is he an angel? Is he God? They're planned seemed to not work on Lucifer. Can we expect the long awaited showdown with Michael? What do you want and expect from the next season. Other then the fillers I have to admit the season was really good, the last episode was kind of a bust, but the ending was really sad. I was almost gonna cry when Dean was lying down all bloody and sad. Give me your opinions?
