*Spoiler Alert*
This is definitely a copy of The Cabin in the Woods , but actually better made. I mean the first half of Cabin in the Woods was kinda boring. This movie was interesting throughout except for a prolonged ending. And respect to Shamalyan for making it kind of counter culture, not putting in any gay scenes and making the couple look like the bad guys which in the end they kind of were. They waited way too long to sacrifice one of them, which cost millions of lives. Good fictional rendition of the Book of Revelation and the four horsemen of the apocalypse.
