Tobe Hooper's Night Terrors is a low budget horror film with a few pinches of nudity (the scenes with "Genie" played by Zoe Trilling and "Sabina" played by Alona Kimhi are particularly good!).
In short, the dialogues are very poor, the plot and the setting are pretty good, and the special effects are average, while the acting is below average with William Finley's performance being pathetic. Moreover, Robert Englund does a much better job as Marquis De Sade than as Paul Chevalier. In addition, it was interesting, though not that surprising, to see Zachi Noy from the Lemon Popsicle series, since the film was shot in Israel.
The movie could have been more graphic, but it seems that the director was holding back for some reason.
Nevertheless, what with the horror and the sexy scenes, and as far as B-movies are concerned, the film is decent.
Overall, far from being a masterpiece, it just might provide for an evening's entertainment if in a really silly mood and/or intoxicated.
