Originally posted by Esau CairnVader had characterization as a ruthless, brutal, but ultimately emotionally fragile and even trouble old man. He hated the Emperor for what he did to him, and would entertain delusions of rebellion, but was so pants-shittingly terrified of Palpatine that those delusions never were made a reality, until he was inspired by Luke, his own flesh and blood's, courage to take matters into his own hands and save the galaxy. His helmet is removed in his last few moments, revealing the broken man he is, yet he is smiling, glad to finally have freed himself from Palpatine's tyranny, and happy that his son was able to avoid the mistakes he made.
I'm saying the villains had shallow characterisation...everyone remembers their "catchy" names but Vader & Bobba for example, did little on screen but stand around looking menacing.Vader had a sabre fight in each movie & Bobba went from standing in the background of Empire to his quick demise in Jedi.
This is just OT.
Characters like Tarkin are also more memorable than Boba Fett, as is Palpatine himself.
