split isn't really a sequel to unbreakable
when split came out a lot of people bitched about the weird way it was "tied to" unbreakable
being in the same movie universe, apparently, but really not a sequel per se
the whole plot of glass is basically the main hero from unbreakable fighting the villain guy from split
so you'd need to see at least one of those first 2 movies to figure out what's going on in glass
but not necessarily both movies
alot of people in america have seen only split and glass and have never seen unbreakable
but sam jackson's got a lot of screen-time in glass, playing the same character he played in unbreakable
if you've seen unbreakable but not split, glass works as a sequel to unbreakable
