Interesting. I thought both Night Strangler (which I personally prefer to the first movie) and Burnt Offerings were well crafted, fine films, though of course each is very different from the other. The evil chauffeur in Offerings gave me genuine creeps, and I'm a hard sell when it comes to that sort of thing.
I tried watching a bit of Supernatural--didn't work for me. I think I am the wrong age and cultural background for the series.
