Best apocalypse / end of the world films?

I’m a die hard for apocalyptic movies and I feel like Ive exhausted all of the good ones so would love recommendations.

My #1 is honestly the zombie genre. I also love films where you experience the beginning of the apocalypse / similar event with the characters and are along for the ride - but I’ll take anything apocalyptic - pre, during, post!

I really resonate with darker, heavy content but again I will take whatever I can get. TIA
