God, I laugh my ass off at that one. Darth (IN)VADER…Jabba the Hutt…on an on.
“Vader” and “Plagueis” aren’t on the same level at all. “Vader” is subtle; “Plagueis” hits you over the head with how “evil” it is.
As for “Jabba”, it’s not a play-on-words like “Plagueis” is, so it doesn’t count in this respect.
Plagueis is not any dumber, but it’s in the prequels so you automatically have to hate it.
If the Vader had been named, say, Darth Invadus and Palpatine identified as Sidious from the very beginning – but everything else about the OT was the same – I’d utterly hate them regardless.
