With all of is controversy with the Barbie movie and nominations next year we might see an expansion of the pool of nominations
Smaller how TDK changed how the best picture nomination was awarded but we could do the same thing for actor and actress nominations. After 2008 a lot of people felt that the dark night was snub for best picture, so the academy changed the number of nominations that could be awarded for best picture. Originally only five movies could be nominated for best picture but after 2008 the minimum number of best picture nominees was 10. a few years later 10 was too much so they changed it to minimum 5 and maximum of 10 nominations. I think that's a good compromise because some years have very good performances while other years have mediocre, but you can definitely find five performances that outshined everyone else and having a maximum of 10 nominations limits the number of people that can be nominated.
I personally think we should remove the gendered nominations for acting actresses and instead separate them by age. Same way how the Grammys removed gender nominations, but instead for the academy. If you separate them by age, it makes more sense. Most older actors and actresses can't play roles that are for younger actors and actresses and vice versa for young artists. It is also more inclusive for trans and non-binary artists. It also evens the playing field a little bit because generally speaking older performers have more experience so it's harder for younger performers to be nominated.
