No, no its not. It is a comedy. Happy Killmore could be a horror movie though. Someone(with obviously WAY too much time on their hands)has taken the comedy and made it look like a horror/thriller. Its good too! It cracks me up and makes me wish they would have made Happy like the trailer. Maybe it becomes a sequel and this is his life now. No money, no Grandma, no hockey…plenty of rage. Get the popcorn ready and maybe sleep with lights on from here on out?
