I thought the scene where Jack gets on his bike (before the electrical event) was nicely supported by some evocative Beatle-esque mellotron. Gave off a mysterious "something's up here" vibe and got the hair standing up on the back of my neck. I saw this a second time via streaming and I'm still not sure the seaside scene worked. I wish the moment at the door was longer, showing us more of how Jack gets his foot in the door of a perfect stranger's home. Wouldn't that moment be a profoundly moving experience for Jack (or anyone in his shoes)? That would have been a good challenge for the screenwriter.
