“Cain Hill” (*1/2 out of four) was a sub-routine horror show about an amateur group of documentary filmmakers (Gemma Atkinson, MIchael Parr, Alex Zane, and others) who go to the abandoned Cain Hill asylum in regards to a series of unexplained murders and kidnappings that have occurred years earlier but soon find that one inmate is still on the loose and is still thirsty for the kill. Horror fans thirsty for blood and thrills should look elsewhere; this takes forever to get going and isn’t anything special once it does. Can we finally lay to rest the found-footage or documentary-style of horror movies?
