Actually, I liked it. MS. MARVEL is very fannish, which will not appeal to some; and some of the superheroine’s devotees are rather intense about their fandom*. But this show itself was fun. They’re going with ‘magical artifact’ rather than ‘mutating gas’ for the power origin, because… I dunno. Because cramming mutants into the MCU, however hand-waved, is gonna be hard at this point, I guess.
As for any message, so far: …eh. “Being sixteen kind of sucks, but having powers would make up for that,” I guess. Which rings pretty true, honestly. A straightforward teen power fantasy should work out okay.
*Not that that happens with any other superhero in recorded history, of course. I try to take a detached view about this sort of thing: Marvel gave me a nice little Seventies-style government conspiracy movie with superheroes in it, which was cool of them, especially since they also gave me a couple of heist movies with giant Pez dispensers, too. I figure that other people get to have their itches scratched.
