I love Veelk posts, because they are always well thought-out, well written, well argued, and tend to spark at least 15 different discussions.
But yeah, the "tree and raccoon was risky" narrative never really held all that much weight. It became a meme due to superficial outlandishness more than anything.
Luckily, that's only about 1/45th of the man's argument.
Thanks for the kind words.
As far as the racoon and tree, eh, it's not a hill I want to die on and I agree that it's not
that outrageous in terms of basic space opera genre practices, but I still think it was somewhat risky given that the established tone of the MCU wasn't this outlandish and GotG changed that. Anecdotally, I know many people who had reservations about it specifically because they thought that Marvel was starting to become too silly once they saw the GotG trailers. I can agree that perhaps it's overblown, sure, but it's not nothing.
I still don't see how that's a risk. The MCU had established itself by that time (remember this is after movies like Iron Man 2, Thor, The Avengers, Iron Man 3, and Thor: The Dark World) as moving towards a heavier focus on humor. Some would argue that focus was always there. Guardians of the Galaxy just seemed like a natural evolution of that formula. The Captain America movies were really the only ones taking themselves somewhat seriously due to handling more serious themes. They're the outlier in the Marvel formula.
Well, I disagree with your assessment that marvel started leaning heavier on humor. I personally didn't see a greater trajectory to humor for any of those movies. In fact, going by those same examples, I could easily make the argument that the MCU was getting darker and more serious. Iron Man 2 had Tony struggling with his incoming death, Avengers had them face the biggest threat they had yet, Iron Man 3 was straight up about PTSD, Thor: The Dark World escalated Thor's romance with Jane from a lighthearted grounded connection to epic starcrossed love drama where she was in danger of dying.
Marvel makes their movies around the Comedy-Drama-Action triad and they're all reasonably balanced against each other in most of their movies. Sure, they're always funny, but as Terry Pratchett once said, funny is NOT the opposite of serious.
Guardians of the Galaxy is definitely a slight exception leaning more heavily on humor than the others, the same way the Captain America movies are the exceptions by leaning more heavily on the drama aspect.
