To prepare, we watched the original 1978 film. That was quite good and holds up fairly well 40 years later. Now, for the 2018 film, which supposedly ignores all but the 1978 film canonically speaking, was good. It captured some of the old creepiness but it misfired somehow. It was well made but I can't quite put my finger on why it should have been so much better. If you are into the genre, it's a must-see. Bring popcorn.
