1) It's kind of strange that on dramabeans there's more coherent and thoughtful critique than on tumblr. The entire last episode was a plot hole after a plot hole and deus ex machina. The only thing i can agree on is that the creator of W became a monster. Everything else is wishful thinking. Han Chul Ho didn't cause his happiness unless that bit is referring to the creator. Kang Chul was not created by the dad and he was always human. He can't become human.
