Shirley Jackson just isn't for me

As a beginner I tried to get into her works, listened to her short story 'The Intoxicated' and boy that was depressing and I couldn't get the point of that story. Two strangers meet at a party an adult man and a 17 year old girl. The guests don't mind them. Both of them have a conversation at the kitchen and she speaks about how the entire world might get drown one day and we will all have a new way of life and sorts and won't read ceaser. Later on he meets her dad and both agree that she's a remarkable girl. I simply don't get it. The story doesn't seem to have a point and kinda depressing.

I looked into other works by her and it's still very depressing. I guess Jackson's work is simply isn't for me. Maybe I'm too dumb to understand idk? I'm currently listening to Willa Cather and she's so much better.
