“Big Bad” (*1/2 out of four) was a big bad bore about a group of young brats and bad actors who spend the night in an abandoned jail for a school fundraiser when their chaperone suddenly vanishes and a vicious beast is on the prowl. Amateurish mix of teen comedy and adventure movie never gells. May remind some of early Spielberg work like “Close Encounters Of The Third Kind” and Rob Reiner’s “Stand By Me” but viewers would be better off re-watching those masterworks than this dud.
