I'm extremely keen on watching all kinds of movies in all genres, and at last count I've watched around 30,000 movies. The truth is that this one had a good premise, but surely the screenwriter "forgot" to give some pages to the director and he didn't notice. Or else the editor received an unfair salary and "murdered" the film in the Final Cut ( sorry for the infamous joke ) The "Hitchcockian" touches excited me at first, until I realized it was a cheap copycat that didn't see all of the Master's work from Suspense. The plot has dozens of loose ends, the main actress confuses "indifference" (which she showed in the film) with "I'm confused about what's going on". Don't waste time watching, run away!
