Really? The ending was the best bit for me. By that point, I wanted the world to end; it felt like the less unjust outcome. "Maybe...the world should end?" - yes! Exactly! That's how I felt the filmmakers wanted the audience to think; the fact they actually had the characters stick by each other no matter what, even though it meant the end of the world, really that was pretty enjoyable. Not a win, but the biggest '****-you' they could deliver to the demons.
Yeah. Those japanese school girls really deserved the horrible death that our heroes decided to bestow upon them. I don't buy it.
