Rightly assuming we all know the story by now, this isn't really an origin tale; it's more about learning lessons. He's already got the powers and a suit, but at 15 his wants exceed his abilities. Holland's Peter is acrobatic, clever and witty, but not overly mature as is befitting his age. There's none of the overt awkwardness of Maguire or the occasional meanness of Garfield. It's all different enough to make this fresh, and more importantly a much truer representation of the character from the comics.
I didn't think I'd be calling a Marvel film mundane, but here we are. Not in a bad way mind you - that grounded quality comes back not just in the environment but also in the characters. This is most obvious in the villain. It brings me great joy to say that Michael Keaton gives us a great villain in The Vulture. His standard kookiness is on display, but with both honour and malevolence mixed in. Like Peter he's had a rough time, but he chooses to deal with it very differently.
Leaning fairly heavily on the themes introduced in Iron Man 3, Spider-Man: Homecoming mixes Ultimate Spider-Man with just enough MCU to make a thoroughly entertaining movie.
