We both remembered this as being fairly boring, and at least one of us hasn't revised that assessment. Regardless, it was a huge hit and a widely influential haunted house movie.
Terrible acting, nonsensical plot, blatant ripoffs of much better films, and some brother-on-sister action are just a few of the things that makes this the must-watch film of the Halloween season. There's no better film to kick off our 2017 Halloween series. Enjoy!
