This movie holds up, and remains one of the great comedy-horror movies, for several reasons. The transformation scene, done entirely using practical effects, still looks pretty great (apart from some of the elongated hands moments, but I stress ‘some’), the writing is done with wit and the acting of the minor characters feels pretty real, and overall the story zips along in an uncomplicated way. There’s very little of that most common fault of horror movies -people have to act stupid at some point to drive the story (inadvertently leaving the road to go on the moors is something we’ll ignore for the sake of the entire plot, rather than a contrivance to help drive the plot), and the central performance of Jenny Agutter, David Naughton and Griffin Dunne are wholly believable.
I feel a bad moon rising.
