Worst one for me was none other than Revenge of the Sith, along with that 3D animation shit of Star Wars that was on the cartoon network, mostly for how lame and lackluster both subjects were. Not only that, but the nerfing of General Grievous was a fucking eyesore. General Grievous is said within comics, books, and even the cartoon series of the Clone Wars (2D animation one) that he was basically considered a Demi-god, his tactical mind surpassed nearly every being out in the galaxy, his cybernetics made him impossible to beat (Mace Windu was the only one that managed to go toe-to-toe with General Grievous and it ended in a stalemate), and best of all: his warrior spirit that made him a deadly foe to face. He wasn't a coward, he always rushed in for a worthy opponent to kill, and his heart was filled with hatred for the Republic, which is understandable on why before Disney butchered the lore. His reflexes were pinpoint accurate and faster than nearly every jedi in the counsel, save that of Yoda and Mace Windu, which gives insight on how to actually SURVIVE Grievous' onslaught: you have to be just as high in offense as Grievous, basically two fires going at it with one trying to snuff the other out. He was a fucking badass. Until they made him into this sniveling, cowardly mustache-twirler that has no real goal than "KILL DEM JEDI CUZ I EVUUL". The Kenobi vs Grievous fight in the movie was so awful, any true Star Wars fan probably cringed at that entire scene to the point they probably wanted their eyes stabbed out. That's what happens when you write such a badass and then realize "OH SHIT, he's not the main antagonist or good guy! Errr let's just cram his death here and move on!"
