Why He Was Betrayed and Beaten

 * 1) He's not a threatening villain in the Last Jedi.
 * 2) His characterization is inconsistent: In The Force Awakens, he was noticeably "gray" (stoic, fair toward his henchmen, and respectful of his enemies). But in The Last Jedi, he's suddenly a standard villain (bombastic, an abusive boss, and suicidally arrogant).
 * 3) The inconsistency where he was a gigantic dark lord in The Force Awakens, but was reduced to a smaller size in The Last Jedi for an unexplained reason.
 * 4) He barely even fights against Rey.
 * 5) His gold robes look ridiculous and not even more Sith-like.
 * 6) He dies anti-climatically by Kylo Ren.
 * 7) The explanation of him being a Palpatine clone, who was supposed to turn Rey to the dark side conflicts with his trying to get Kylo Ren to kill Rey.
 * 8) * It also contradicts the material stating he'd been around since before the Empire.

Redeeming Qualities

 * 1) He was decent and more tolerable in Force Awakens.
 * 2) Andy Serkis does a good job with the material he's given.
