https://youtu.be/9eJXB0FQPD0 - good analysis on why Snoke in the ST doesn’t work like Palpatine worked in the OT.
I think the guy provides analysis but whether it is useful or not depends on how you see Snoke as a fan of SW. I did not care about where he came from in the same way I didn’t care about where Palpatine came from in ANH. I thought about this for a while and came to the conclusion that my thoughts and feelings about Sidious did not change after seeing the prequels…at all, amazingly.
I think has a lot to do with why the guy exists at the base level…to be a villain. Having him be mysterious in ANH made him more menacing and scary. Same with Snoke. I see him in exactly the same way I saw Sidious and did not have any desire to really know where and why he came to be in TFA. Of course I was curious but it was minor.
