For 2020 I will be listing what I feel are 366 essential horror films that all fans should watch. This list will include many of the best horror movies ever made as well as important films that I believe should be watched as well.
Dir- Fritz Lang
Set in a dark industrial world, M is the tale of a frightened city held hostage by a serial killer who is targeting children. The search is so intensive that the local crime organization joins in because the killer's reign of fear is detrimental for their business. M was an intense film for its time with a subject matter that was a warning to families about watching out for their children. A compelling German Crime/Drama that has excellent horror elements and will remain a classic of all three genres. Peter Lorre's first film and one of director Fritz Lang's greatest movies.
