The Ending Of The Block Island Sound Explained The Ending Of The Block Island Sound Explained Netflix By Robert Balkovich/March 12, 2021 3:02 pm EDT Ever get the feeling that something is watching you? Not just a nosy neighbor, but something much larger and more profound? That unnerving sensation resides at the heart of the slow-burn horror movie The Block Island Sound. As the title suggests, the movie takes place on Block Island, which sits off the coast of Rhode Island. Local man Harry (Chris Sheffield) has been having a difficult time dealing with his father, Tom (Neville Archambault). Tom is a gruff fisherman who was always a little inappropriate at the best of times, but lately, his behavior has been erratic. Especially concerning is his new habit of taking his fishing boat out to sea in the middle of the night.
