I'd say the effect was like zapping between TV
channels, but that metaphor is probably meaningless to the target age demographic that film addresses: it's more like
surfing between websites on a low concentration threshold, or rather like leafing through a few pages of a comic, before tossing it aside and skimming another from the same giant stack, then going back to your first title
again, before eventually realizing that all along you've been reading parts of the same vast, wildly complicated story.
