I bounced off the book Project Hail Mary in a way that I did not on The Martian. Quit about a third of the way through. (Which is ironic, based on what I remember of the story.)

I'm not sure why it didn't appeal to me. Perhaps I changed too much in the intervening time.

I'll give the movie version of Project Hail Mary a try when it becomes available on streaming. But I won't go to a movie theater, or pay movie theater prices for it.
