The Clever Incorporation Of Artists and Song In The New Avengers aka Thunderbolts*:
Son Lux is a band.
This is a big deal because up until The New Avengers every movie that takes place in the MCU's score/soundtrack is by a single composer, not 3 people, and I think part of that anyway has to do with the emphasis of family dynamic being presented like it just hadn't been previously, not to say that it hasn't come up or been implied, and of course no matter what there's been that range of looking out for each other, such, but it just feels more... There's that necessity of being there for someone right then, in their darkest hour, even when it literally hurts, even when they're pushing you back, and you have to face those fears, those demons, to overcome and not give up on them; family can practically drive you mad, but they're also gonna be there to help you retrieve your sanity, and that's really the underlying lesson as it were of that film.
This Starship bop has its own bad reputation.
Every member of the New Avengers had had some range of being treated like they're no good when they're really so much more than people have assumed, and fully deserve to be called heroes, so with "Nothing's Gonna Stop Us Now", the parallel is that it originally was from a movie called Mannequin, in which a man falls in love with a plastic shop model that comes to life, and believe it or not, it's actually pretty cute, but obviously not the sort of thing to wow critics, which, consequently, its theme song got caught in the like crossfire of that lambasting and for a while was also considered "awful" when it's actually great, much better than the source (even with that not being bad as many think), and there's no better theme for a bunch of misfits who are undermined and misrepresented merely 'cause of where they come from or situations they were previously put in that they didn't fully understand and or weren't even their fault, just saying.
