Please watch it with the original, Japanese audio and not the dubbed verison.
The story was truly amazing, realistic and captivating.
Not a single scene felt rushed or slow, pacing was perfect. The story really captures Japan in the 80s and the porn industry of that era. The story is basically a fight for the market share of the industry despite the government restrictions on uncensored pornography.
I don't know how much of this is true and how much is fictitious but one thing that I do know is that this series is extremely entertaining and informative.
It is definitely worth a watch.
