I couldn't help but think of Hostel, Frontière(s) and Vacancy after watching this film. It's not that this film is a rip-off or anything, how could it be? It was made 30 years before all of them, but it just inspires thoughts towards those similar titles because I saw them first, even though Frontière(s) and Vacancy were way better.
It Happened At Nightmare Inn was overall a very satisfying and fun film. It's about two sisters who run a family inn and they are secretly murdering everybody who they believe to be bad influences and or just bad people because of their religious beliefs, the sisters' beliefs, I mean. It's not the most profound plot, but who really cares about that with this kind of movie? The movie keeps you interested and it definitely entertains. The characters were good, plot was decent, acting was perfectly fine and the movie's atmosphere gave it that creepy, yet corny B-Movie touch that I felt comfortable with because I had felt this atmosphere before. This movie is pretty good for a low budget slasher and as a movie itself it is very enjoyable. Watch it when you get the chance, though don't be expecting too much and don't be too harsh on it if you have seen other, better, similar films.
