This extremely boring German shot-on-video horror film is shoddy even for amateur standards. Its running time is about 70 minutes (there has been a re-edited version in 2000, I think, with added scenes, but it doesn't make things better) and almost nothing at all happens. There are two or three quite gory scenes, but they are lousy (compared with other German amateur gore films from, e.g., Olaf Ittenbach or Andreas Schnaas). The plot is inexistent, because the thin story line gets blown up that much that it gets lost somewhere in the middle of the film. The final scene also makes no sense and has no connection whatsoever with the rest of the film.
Don't get yourself misled by the tagline "the latest horror shocker from Italy", because even though it has been made in Italy (in a way Andreas Bethmann's holiday video), there is nothing comparable to the even worst Italian horror film - "Insel der Dämonen" is inferior to almost every other film of its kind; except, maybe, Todd Sheets' "Zombie Rampage" which was made ten years earlier. 1 out of 10, which still is too much for this unbelievably annoying dog turd of a film.
