“The Devil Below” (*1/2 out of four) was a wearily derivative horror thriller about several explorer friends (Alicia Sanz, Adam Canto, and others) who venture into the Appalachian mountains to uncover the reason for a series of coal fires but instead find (yawn) an ancient creature intent on killing them and all of mankind. Hard to believe the same story could be re-told in at least 3 horror movies released in the same week but seeing is unfortunately believing. Also hard to believe this was made by much of the same crew who made 2012’s “The Chernobyl Diaries” which was stylish and scary but this one is a long-winded bore. Will Patton is wasted in a minor throwaway role.
