Scrape IMDb keywords and the Parental Guide

The first link seems to be the most similar to my suggestion but damn, it’s really disheartening seeing that thread getting ignored for almost 5 years.
The fourth link talks about different “keywords”, I’m specifically talking about the existing IMDb keywords while they’re talking about something akin to Netflix subgenres (or atleast I’m not aware of any source where you could scrape such data).
The fifth link is kind of interesting but TMDb keywords are lacking when compared to IMDb keywords.
I’m conflicted wheter I should close this or not.

Now, I’m only human and I make mistakes. I sometimes forget some tags, and I haven’t seen every movie in my library, so some movies are left untagged.
