I liked. Obviously the ending was messed up. but there was a great social critique, that the real monsters were humans. I found the ending confusing and strange so I think it's not just that, all this hate towards the series is unnecessary I really liked it. but each to their own opinion.
I liked the whole series and found it super interesting I didn't stop watching. so I liked it and give it a 9. i do believe there will be a 2nd season. and the ost and the characters are so funny omg, taking away the kills..
