I've been searching to find a movie that's about monsters/mutant humans living underground in a cemetery catacomb thing... there loads of these monsters living under the ground and then there's some teens trying to help them one of the teens is dating the monster... I think it was set in the 80s I was a really classic movie... near the end of the movie some police and humans start to fight the monsters... thats all I can remember I was only a kid when I seen it... got any ideas what it could be please help ?
