Arguably my favourite moment in the film is right near the end, just as "Ain't No Mountain High Enough" starts to kick in, and we get that extended slow zoom-in on Quill's face, sadness etched in his expression and tears welling in his eyes. It's such a powerful moment for me, as it highlights the sadness and melancholy at the core of Quill's character, while also paving the way for closure and future happiness. It's a moving happy/sad moment that chokes me up in much the same way the similar closing moments of Super did.
And more than the moment itself, I absolutely love the wider implications of the lead-up to it. So many superhero movies are about that father/son relationship. Historically, Jor-El is presented as the key absent parent in Superman's life, while it seems Thomas Wayne occupies Batman's thoughts more than Martha Wayne despite them both dying in the same alley. The list goes on and on. And with the revelation about Quill having an alien father, we can maybe expect that thread to continue in future films. But not in this film. I was taken aback by just how disinterested Quill seems to be to learn about his father. It's like a "Huh, weird," but then his thoughts immediately jump to his mother, the parent who WAS there for him throughout his childhood. It goes starkly against blockbuster logic, as storytelling 101 would have Quill marching onward with a new quest to seek out his father as the credits start to roll. But I love how instead the true climactic character moment for Quill was allowed to be him coming to terms with the loss of his mother. That totally connected with me on a personal level. I never knew my father, it was my mother who raised me. And I never felt a void in my life, like I needed to find my dad. Instead I appreciated my mum for being the one who was there for me. And so that final message hitting home how much Quill's mother loved him, that was just really moving to me.
