The Importance of Snoke

I forgot R2 D2 was supposed to be in this movie until this moment. And then he just does the one thing and then disappears again. I would have loved it if they had just run like after Snoke dies because I was kind of wondering, like, what exactly are those guys? Are they like trainee Sith? Like so many other things. They're like, oh, don't hold on the seriousness too long. We're going to have to have a sort of half joke or a sort of meta comment about it.
