I'm writing this review as of chapter 683.
Grammar: Excellent, the translator has done an excellent job at translating this story and I couldn't find many mistakes if any.
Updating stability: Also excellent, from what I've seen the translator has already finished translating this novel.
Story development: Only so-so.
The story started very good and progressed very logicality and appealing, however from about chapter 150~ the MC started to do things that were very frustrating to read.
His various actions gave the feeling he let people and mostly some female actresses exploit him way too much, and from chapter 400~ he even gave out blockbusters films scripts he knew from the future are going to succeed to other film companies to publish instead of publishing them himself.
He gave out scripts like Mission Impossible, Men in Black, Jumanji, Forrest Gump, Night at the Museum, Mr. & Mrs. Smith etc, all those movies he gave to other people to publish and distribute, not because he couldn't direct and publish them himself, but for some stupid reason like his dream to rule Hollywood from behind the scenes.
I honestly found myself very frustrated while reading from chapter 160~ but I continued reading because I also somewhat enjoyed the other parts in this novel and hoped to reach the part where the MC would release the superhero Marvel movies, but at chapter 683 I couldn't take the frustration and annoyance anymore which forced me to drop it.
Character design: Extremely lustful, like very very lustful. To give you an idea how lustful he is I would just give part of the list of women he slept with till chapter 200:
1) Jennifer Aniston
2) Julia Roberts
3) Drew Barrymore
4) Virginia Madsen
5) Nicole Kidman
6) Gabrielle Anwar
7) Elisabeth Murdoch
8) Carey Lowell
9) Leigh Zimmerman
10) Famke Janssen
11) Jennifer Connelly
12) Joanna Pacuła
13) Diane Lane
14) Diane Lane
15) Elizabeth Fey
16) Claudia Schiffer
17) Penelope Cruz
And many many more. And he insists on keeping them around as his women, like building an Harem in real world. I don't have a problem with Harem, but this is just absurd.
World background: The author's research on the films and companies around the world as the years in the novel progress is nothing short of stunning and excellent, I frankly think this is the best part in this novel.
