What do you think was the most snubbed non-nominee for the Oscar’s ever?

Personally for me it was Hereditary.

Toni Collette delivered one of the most Oscar worthy performances I have ever seen, all of the actors were fantastic, the music, the direction, the symbolism, it all worked in perfect harmony to create one of the best movies ever made.

But also horror movies are traditionally overlooked and snubbed at the academy awards.

What would some of your picks be?
