The episode was brilliant but things are way out of logic. If God and Darkness are equal in power then how can Darkness defeat God just like that even after being so weak. And how can God die? It is way too illogical that something that has never been born can die. What is worse is God got defeated before even giving a fight. And every angel and demon is God's creation after all so they are just a small part of God's power. How can they hurt the darkness? Brilliantly directed. But logic is too weak. Excited for next episode. Supernatural is getting back on track. Back to its awesomeness. Hope God doesn't die. But I guess He will surely go away. To give more story to next season. :p
