It is one of the best rebirth novels out there. The author has a good focus on the story arc, and doesn't make the MC all-in-one. fair challenges, reasonable and logical harem, and good ending too.

more of a harem-seeking novel than an entrepreneur one.

It is good but too much focus on movie industry, if your reborn in 1978 with memories till 2020. You can and should definitely aim to achieve to more than just setting up a film company But it is written well

decent story, but misses out out on detailing the macro picture the problem is does too much of repeat explanations instead of dialogue.
