If there is one thing Snoke presents, it is style. The gold robe is ready for those cold Winter nights. He has a smile with a grandfatherly aura to it and quite an impressive throne room too. However, everything else about Snoke is the opposite.
For one, Snoke holds a large amount of suppressed anger. His grueling voice as he calls on Kylo Ren to retrieve Rey and his creeping commentary as he tortures her with his force prowess are just two examples. He even destroyed an entire system in Hosnian Prime out of his rage against the Resistance.
There was also something off about Snoke, though. And it adds another dimension knowing that Emperor Palpatine was the one pulling Snoke’s strings all along. So if you invite him to your party, you mine as well be bringing the Emperor along too.
