I didn’t actually like or give a shit about Snoke in TFA, and agree a retread of the old ‘master and apprentice’ thing would have been lame/predicatable. I also think the way in which he died (and thatbwhole throne room scene) was pretty good.
But after setting Snoke up in the last film it would have been nice to at least get some insight into who he was and why he was doing what he was doing so that Kylo’s destruction of him could have had some meaning/impact on events. As it stands I didn’t care about Snoke before or after his death. He was a cardboard cutout villain. They may as well have given him a moustache to twirl.
