The academy clearly doesn't agree with you there.
So the movie had at least one Oscar worthy performance, as well as according to the academy, at least 2 oscar worthy original songs and Oscar worthy screenplay, but the movie is also crap?
Any way you slice it her not being included doesn't even make sense, even internally removing all other factors. Even if you personally didn't like the movie it is strange the academy would consider everything Oscar worthy except the person who actually made the thing.
Thats the thing thats most baffling about it. Its not like they ignored the movie. I see more from a confusing angle rather than it being some orchestrated thing, although I'm also not going to immediately discount arguments suggesting that bias was present here. I would have to have seen all the other movies to make a statement on that however.
Ultimately it is what it is, even if it wins absolutely nothing, people only really care about oscars for 2 weeks before it drops so they can validate/argue their opinions on movies and then np one talks about them for the rest of the year. Barbie being the most successful film of the year is a far greater achievement, especially given how bad the year was box office wise.
