Elaborating more on why I find this so striking: so we all know that Weir kind of sucks. And I think most of us are aware that the PHM novel was intended as Weir's self-insert story, about a man who is tragically misunderstood and betrayed by an Earth which doesn't value him, and makes an idealised male friendship among the stars and leaves Earth forever. And how, due to Weir's complete lack of self-awareness, the story instead becomes the story of a man who is chronically unable to recognise when people value him, and deliberately self-isolates and shields himself from his own lonliness with logic. I think we all know this.
But building on this, the two directors of the PHM movie saw this read, prioritised it over Weir's intended read as both more accurate and more compelling, and built the movie around that read as a basis. Particularly striking to me is a moment from an interveiw about the movie's score. One of the directors says that, intially, they tried ominous and scary music to accompany Grace waking up on the ship, but it didn't feel right. So they instead alighted on a piece of music that said, in the director's words: "Poor thing. He's going to be alright. He just doesn't know it yet."
This quote is hugely important to me, because it underpins the dialogue between the book and the movie, and can almost be interpreted as a direct dialogue between Weir and the directors. Weir writes a book that says: here is the world. It rejects me, and I don't feel valued. I deserve better than this, and instead of examining why, I choose to externalise the blame. And the director, another man, but one with a more healthy mindset, looks at this worldveiw that Weir has presented to him and says "poor thing. you're going to be alright."
So this is why saying "Project Hail Mary is answering the question…. can adult men make friends if the universe is depending on it" is funny to me: because it's acknowledging that dialogue between them in a very explicit way that leaves little room for interpretation. It's acknowledging that this is about adult men having issues with making friends and forging emotional connections, due to their own self-imposed limitations, and thereby also acknowledging that Weir has these limitations. It's very bold. And the funniest thing is, for it to have made it into the cut, it must've flown completely over Weir's head.
