LOL! You are correct - artsy wasn't the right word. I don't know how I would explain it.
A Star is Born is a remake, so meh.
Green Book - the plot I heard about it reminded me of Driving Ms. Daisy, so I lumped it into a remake category. I didn't know it was sorta based on real life. I did know it was a Farrelly brother movie, and I held that against it. I don't care for their humor overall.
Bohemian Rhapsody - Meh. I enjoy queen music, I don't need to see a biopic about them.
Vice - not in the mood for political.
I guess a better way of putting it is: The best picture nominees seemed like each was directed towards a specific audience. Like, here's one for those who like period pieces, here's one for the geeks, here's one for the music set, here's one for the biography fans. Does that make more sense?
