Terrible, they literally took away most of the good qualitaties of the manhwa and replaced it with unnecessary characters and excessive blood and gore. The acting from the brother is nothing like the he was written, so disappointed. Next time focus more on the story than trying to just make the monsters as creepy or weird looking as possible so you don't lose the magic that is sweet home.
Oh it's let's not forget the terrible music choices. Didn't help the scenes at all, just loud and overly corny action music.
