All in all, The Open House was a passable horror. Not particularly good or bad. Just passable. The problem was that it focused too much on the buildup but the reveal of the culprit did not really pay off. The script also turned the rest of the cast into cardboard characters that viewers have seen countless times before. Of its 1 hour and 34 minute run, only 20 minutes really held my interest and I’m not sure if that’s enough to set this film apart from the rest in its genre.
