I think I've watched 22 on the list (mostly from the 90s).
I don't find the Oscars very relevant these days; they feel like they are more about what the current fad is/what is popular at the time rather than what is actually the best film of the year.
For example, I understand the cultural importance of Black Panther, and it is a film I enjoyed a lot, but a nomination for best picture? No. It wasn't even the best Marvel film in the last year...
Good luck with your viewing, however, there are some jolly good films on that list!
