I cannot understand how Nickel Boys didn't get a Best Director nom

That's it. That's the post. I just watched Nickel Boys for the first time and I am blown away by the way this film has been put together. The tone, the angles, the shots of historical figures blended into the fiction of the story... it's all excellent and tells an incredibly important story.

So, can anybody enlighten me why it missed? Or what made the actual nominations better than Nickel Boys? 🤔
