“Why Hide?” (*1/2 out of four) was a by-the-numbers bloodbath about a group of friends (Charlotte Atkinson, Elsie Bennett, Lorna Brown, and others) who gather for the Christmas holidays in a remote lodge on the English countryside where things soon go awry and they all start getting murdered one by one. Movies like these make you realize more and more how much the original “Halloween” and “Friday The 13th” were works of art by comparison. Striking cinematography by James Cook is the only asset here. “Why Watch?” would be a better title for this time-waster.
