Not well would be my guess.
I think I have explained how Skam works before but I'll go over it again;
Short clips are uploaded "in real time" (i.e. a clip that takes place on Tuesday 2pm gets uploaded on Tuesday at 2pm). With all of the week's clips being folded into an episode at the end of each week.
There are also social media posts uploaded in the same manner which are made by the characters. So each character have instagram accounts, etc.
So it plays to the supposed strength of Facebook, but I wonder how their Facebook Watch service will be integrated in Facebook/instagram. Even if (and that's a big if) the show is good it can't surmount a bad service.
edit: From Deadline's article so y'all can understand just how big Skam was:
The show, which debuted on NRK platforms in 2015, uses narratives in real time with unknown actors and scripts that are geared to a 16 year-old audience with a focus on teen issues. The show scored huge ratings among young and adult audiences in Scandinavia, growing its weekly audience from 24K to 1.262M (Norway has a total population of 5M) and outperformed many TV and streaming primetime hits in the territory. Episode length varies from 17-50 minutes.
2nd edit: you know what, burn it all down:
What could possibly go wrong Facebook? You can't say you did notsee it coming considering Youtube's issues with advertisers and the content they chose to not curate.
