Reading the other reviews, I believe that most people expected to see a spandex-dressed superhero series. Stan Lee's name in the very title of the series would cause that.
This is a police story. Police detectives who have to deal with something seemingly impossible. It is the concept of ordinary people who have to deal with extraordinary situations.
It is closer to "Fringe" than anything else. Not much action, but plenty of mystery. It has an intriguing plot (with a few minor flaws) that keeps interest quite high. Acting is OK, nothing exceptional, but nothing disappointing either.
Overall this is a great story, told in a satisfying way. As I am a fan of the genre, I consider "Lucky Man" to be one of the top 3 series of 2016.
