This is a movie that works around a detective taking the confession of "the strangler." 90% of the movie is between the detective and the strangler talking. We are taken briefly through each of the murders, perhaps too briefly. There are a couple sections in the movie towards the end where it jumps ahead in time way to quick. It feels like the director decided to just finish the movie and wanted the quickest way there without resolving much of anything. So while you may have been into the story you feel cheated by the abrupt ending.
It is apparent that it is a low budget film but thats not all that important since there are few scenes that are not the confession scenes. I would assume that is why the director failed to go into detail with the murders individually (to cut costs). As a suspense it is OK... an interesting watch. If you don't expect a lot from the movie you won't be disappointed.
