I rated this a 6.5. So a few random thoughts.

-I'm new to Japanese drama. I wasn't familiar with the main actor but he was very good in this. Also very handsome in many scenes.

-The OST was really good.

-The first 3 episodes were amazing. Really set the tone. There were characters to root for. I was hooked.

-Episode 4 it started to go downhill but still watchable. By episode 5 I was bored and quit the series for a couple of weeks. I started it back and completed the remaining episodes. It just got worse for me.

-For me the hardcore sex scenes were not an issue per se. In the first episodes they were titilating and sexy. By episode 5, the main character is saying he wants more eroticism yet the hardcore sex scenes in the series were getting more cheesy and quite frankly boring.

-The scene with the Kuroki lady walking in and demanding to have sex with the ML for the first time was so unrealistic. I know there are cultural differences but no way it happened like that. They made her seem like a sex zombie.

-The scenes with Kuroki's mom in reaction to finding out her daughter is doing hardcore porn was also unrealistic. I think maybe it was just bad writing.

-The Yazuka/gang/mafia stuff was overkill and honestly boring. I didn't care about these old gang dudes.

-Also when I read about the real guy behind this character, Netflix really cleaned up his image. For example he was arrested in Hawaii for using underage models in his porn, yet Netflix didn't address that at all and made it seem like he was arrested just for shooting porn in illegal locations or something.

-Overall, it is worth a watch mostly for the main actor's acting ability.
