My recent Oscar nominee viewed was Triangle Of Sadness. Nominated for best picture as well as director and screenplay (both for Ruben Östlund). He directed the phenomenal 2014 Force Majeure and the highly regarded 2017 movie The Square (which I just added to my To See list).
I really liked it as well. The movie is divided into three parts/chapters and it's almost like three different short films with characters from one chapter sometimes appearing in the next. I liked the first chapter more than you. I'm a big fan of Harris Dickinson ever since his film debut in Beach Rats. This first chapter of the movie is like a stage play with a male and female character verbally sparring with one another for understanding and perhaps dominance. It's very well written and the two actors nail their parts. And I agree with your spoiler comment completely!!
I like Woody as well, I last saw him in Zombieland: Double Tap and he was perfect. His role here in Triangle of Sadness is another good one. He's perfect.

With this second chapter of the movie, we get to hear the director on the DVD extras talk about how he stages a showy dramatic/action scene in his movies to give a breather to the audience. The first and third parts of the movie are more dramatic, so some escapism in the middle lets us relax before the finale. Another DVD extra is how one of the producers becomes an extra and is featured in the hallway scene as the ship's fate takes a turn for the worse, specifically the "flowing ravine" section.
I just finished the second of my “Eat the Rich” double feature
Triangle of Sadness and wow! Not the best movie ever but it kept me interested throughout and it was a journey.
It sounds like I enjoyed the movie more than the rest of you did. The third and final section/chapter I thought was amazing. But I always love the
types of movie. Dolly de Leon as Abigail was amazing. I'm glad she was nominated for best supporting actress at both the BAFTA's and the Golden Globes. I was a bit disappointed at the
of the ending. (A common pet peeve of mine.) But again, there's discussion of this on the DVD extras which settled me down a little bit.
While this movie was nominated for pretty much every award in many categories, it lost pretty much everywhere except early in the season, winning two Cannes Film Festival awards and three European Film Awards.
