I definitely think life experiences can change your tastes. While I’ve never loved grim stuff I was much heavier into superheroes/action stuff, historical fiction and crime TV growing up and into my 20s too. But after some personal struggles I veer largely towards humor and romance now and can only enjoy those other things under certain conditions. I think it’s because I need to feel some sense of hope as my everyday living experience is full of hopelessness and powerlessness.
