Not that I disagree, and Rogue One definitely went down this path. But TFA not so much - it fairly definitively eschewed shades of grey for absolutes of good and evil, right and wrong. The Resistance are the good guys, the First Order are the bad guys (seriously Nazi-like, world destroying bad guys). If they plan on painting Snoke as more than just an evil, Emperor-esque bad guy, it's going to be a task. Kylo Ren, on the other hand - I can definitely see a conflict building there. And that will definitely be more interesting, unless they simply rehash Vader's storyline.
Thanks! And to be honest, I kept pausing as I wrote that part, because I was thinking the exact same thing. When I rewatch Episode 7 and I see them destroy the planets with Deathstar 3, I struggle to justify it as anything other than, as you said, 'Nazi-like'.
Honestly though, I'm hinging my hopes on that slice of information from the Wiki. But here's my two main reasons why I think Snoke (hopefully) won't end up like the Emperor:
1.
He appears an entire film earlier than the Emperor giving him two full films of development, with no need for introduction. The Emperor only
physically appeared in the last film, so giving him a simple objective made more sense. Also, different times, different directors.
2.
He has an apprentice who needs further training. If Rey is trained in this film in parallel to Kylo, this is already potential to step away from the original trilogy, and do something interesting. Instead of just showing how different they are, they could show how in many ways, they're similar. Either way, this simple fact means he has to be an actual character, a mentor, with a philosophy to teach. The Emperor could just lounge back and shoot lightning because all his work had been done in the prequels (where he has more character).
Now the best way to ruin all of that, is to not show Kylo being trained, make it all happen in the gap between the films (where undoubtedly novels and comics will show us the training instead), and he appears a fully-fledged... erm... Knight?
All that being said, the Skywalker Saga so far is being used for nostalgia purposes. But, as I (perhaps foolishly) argue in it's defence, TFA
is the first in a trilogy. I think we just get a bit more worried, because people were so burnt by the prequels. Hopefully they won't be again.
