World of Light is really weird from a tonal perspective. The CGI cutscenes are needlessly dark, falling into the same pitfalls as Subspace, but the actual mode itself is really lighthearted, silly, filled with tiny little references, and generally feels in line with what I'd personally want from a Smash story mode. It's a shame that WOL is - like many Nintendo creations - just summarised to "WOAH, EDGY KIDS' GAME!" based on the intro and bad endings alone, because honestly spirit battles and the WOL world map are one of the rare highlights for SSBU IMO
