I haven't seen such a charismatic, fleshed-out villain like Landa in years. Heath Ledger's Joker comes close, but even then, I found him more exciting and appealing. Landa, however, disgusts me, yet makes me smile. I think it's due to the fact that Landa has basis in reality and didn't ever come off as over-the-top or campy; most actors substitute camp for charisma which prevents them from being truly terrifying.
