I like the concept that every character is unsympathetic, including the protagonist. This makes it much more open to who's up to what, and what is going on. However, the lengthy exposition at the beginning is annoying. There is potential in slowly building up the situation and characters; but that wasn't done here: flat characters. Too many clichés. And clichés save time; that's their positive side. They don't need to be repeated. Also, a bit too much moral and political correctness, which is then dragged out. Speaking of which: it runs well over two hours, but fortunately, unlike TV and cinema, you can speed up playback when streaming. The mystery is a "classic" (that is, old and proven, Hitchcock and others). But that is not the problem here. It lacks tension and doesn't really captivate you, not even in the most dramatic moments (which you can tell from the music). And when the plot finally progresses, it stil is sloooow and spells out everything (of the clichés). What became of "show, don't tell"? Solid enough work by all the departments, including actors; but production, script and direction dropped the ball here. Not worth the time.
