Pretty close to a perfect film

Rating: 9/10 (15 August 2018)

I rate this very high on my best of list for its ambition and intellect.
The script is written on the body of the main character. It's a device that the TV show Blindspot would rip off.
I watched this over and over and over and it took me to a place I did not want to go, because it's very dark but here I go:
The main character is attacked, wife raped, him injured.
He develops a fake condition to scam his insurance.
The insurance investigator figures this out during a flashback in a flashback with the eletric blocks
His wife gets fed up, challenges him, he knows it, and murders her with the insulin.
Sent to a hospital, he escapes and meets up with the cop who investigated the case. They track down the rapist/thief and murder him.
However, the memory condition then becomes imbedded. He became his own fictional character.
The crooked cop exploits a drug deal gone wrong to get the dealer, Jimmy G, murdered.
Jimmy's girlfriend Natalie, the smartest character in the whole movie, figures it out and uses our memory boy to chase off the other dealer looking for the missing money.
Where I got lost is where our memory boy decided he wanted to kill the crooked cop and tattooed it to his body so it would become a memory.
Lenny was never an insurance investigator, his condition is self-delusional. All he did is just the same as looking at a few polaroids and trying to create/remember a past.
Guy is playing 3 characters here. His own character, the borrowed character of the insurance investigator, and his made up personality as the film goes along.
