Although not as good as that terrifying Twilight Zone episode starring Bill Shatner, this movie is definitely under appreciated. The plot is strange with all the Druid rituals, but the oddness of the subject matter adds to the atmosphere. It takes place on a virtually empty airplane which I myself have flown on before. With a full plane, the whole thing would have been a chaotic mess where as this sparse cast allows for a bit more calmness and thought. The characters work together to defeat this demon or ghost or whatever it's supposed to be, but they gradually fall apart as the terror gets more intense. You will recognize most of the actors and they all turn in decent performances. It's hard to pick a favorite, but Shatner's drunken defrocked priest is the most interesting. The special effects are good at times, but occasionally amateurish due to working under a TV budget as opposed to a movie one. The whole package is very entertaining though. When I realized it was coming to an end I was kind of disappointed as I wanted more. Overall, the film really impressed me and after watching this it made me want to look into many more 1970s made for television horror movies.
