Yandere, alpha males and toxic/dark/unhealthy romance

Here is a list of shows and films with yandere characters (jealous, controlling, possessive, obsessive, etc.), dominant/alpha male personalities, or toxic, dark, or unhealthy romance. Be aware that some shows and characters have different levels and intensities of the requirements, this list is just my opinion and is in no particular order.

I am open to your opinions if you think shows or films should or shouldn't be on this list , but be respectful of everyone's opinions even if you don't agree. 

I'm only adding shows or films that I've seen, and these are only the shows/films I've seen so far. Please leave recommendations in the comments, as I'm always looking for more shows to watch. I have a lot of shows on my watchlist, so I will update this list as I go.
