See enough movies over enough decades – five-plus decades, in my case – and you may begin to wrongly think that cinema no longer has the ability to astonish you. But while I'm hardly going to make the case for the superhero adventure being on par with, say, Citizen Kane or the first two Godfathers, or even Richard Linklater's 2014 Boyhood, I'm not sure that any film released since that latter title has thrilled and awed me quite as profoundly as Spider-Man: Across the Spider-Verse.
