I'm kind of amazed that the Snoke Origin Crisis is still so perplexing to some, but a lot of that seems to have been addressed here... 1) Star Wars always starts "in media res", up to and including Episode I. You don't get a five-minute intro like in Lynch's Dune... you get a crawl drawing broad strokes about the state of the galaxy, but even that assumes you "know" a bit about Trade Federations or Empires or First Orders (which are basically so archetypal that not much more need be said). Being 30 years after the OT, the ST naturally starts out about as "in res" as media gets. New evil faction rises from the ashes of the old with a new leader. Simples. 2) Did anyone honestly have a full-on Robbie the Robot "does not compute" inability to understand the story of TFA due to the lack of a detailed backstory for Snoke? Like he's there on the throne giving orders and being called the Supreme Leader but we're not really sure if maybe he's not just a pet store owner whose hologram got patched through by accident? The story is *not* difficult to follow (see for comparison, again, Lynch's "Dune", or, closer to home, AOTC). 3) Snoke serves an entirely different narrative purpose from Palpatine, thankfully, particularly since it's one alluded to but never before shown in the saga: the dark side master being deposed by the apprentice. In fact I know I'm not the only one who thought that this turn of events was practically telegraphed by Snoke's not-too-interesting-or-original depiction, and that, from the get-go, he was there to be sliced up by Ren. The Palpatine-Vader dynamic, where the apprentice will ultimately not follow the dark side imperative but reject it, demands a little more development of that relationship. Snoke's basically just an onscreen equivalent of Plagueis in the PT. Plagueis still doesn't have a canon backstory but that doesn't seem to be a big problem in general. Again, "in media res", on at least some level, is the Star Wars way. 4) This kind of thing literally is what the now-canon ancillary media stuff is there for. If you want to see what kind of a drag unnecessary backstory can have on a narrative, you've always got the shoehorning of the Fetts into the PT for... reasons? ... at the expense of more important narrative beats that needed a whole animated series to retroactively cover. Yes, it would be nice to know how Snoke's corruption of Ben Solo went down, but it can't be "shown" -- the Rashomon flashbacks in TLJ are in my mind among the least effective segments in a film I otherwise like a lot -- and it can't be monologued about without putting the brakes on the narrative flow. It'll be told elsewhere, as it should be.
