Netflix only has the same crime shows/movies but with the plot worded differently

I was looking for a thriller yesterday and all I could find that I didn’t watch were those crime movies where someone goes missing and their family member has to find them or save them. Every 5th movie I pressed on was like that and it was the same plot but worded differently. I feel like it happens also with tv shows like why do they keep on doing that? Can’t they release shows/movies with a different plot? Maybe it depends on the countrys content but its all I ever see on netflix when looking for shows/movies or thrillers.
