I have rarely hated a bad guy as much as I hate Voss in Indiana Jones And The Great Circle
It's not just because he's a Nazi. It's because he's a smartass Nazi. As the main antagonist in Indiana Jones And The Great Circle, Emmerich Voss vacates the archetypal armchair usually reserved for secondary fascist goons, so that he can goosestep straight into the big boy seat himself. He smiles with all the sleaze of right-hand-man Major Toht, the grubby gestapo who gets that right hand burned in Raiders of the Lost Ark. Yet he also engages in the pseudo-intellectual trash talk of the main archaeological rivals to Jones, like Rene Belloq or Walter Donovan. He is a hideous grab bag of all the things that make an instantly detestable villain in the series. But there's something else. Voss is so immediately and gutturally hateable because he resembles a type of racist encountered not in the 1930s, but one you've probably met today: the asshole you meet on the internet.
