"In a series filled with silly, in-your-face frights, Mr. X is a cleverly implemented and even subtle horror that's one of the Resident Evil franchise's greatest achievements.
Mr. X is the best thing Resident Evil, as a franchise, has ever done.
I say this knowing, of course, that most people are going to disagree with me. In fact, I'd daresay that longtime fans of the franchise have come to a general consensus that the series' biggest, baddest baddie is Resident Evil 3's Nemesis. And trust me when I say that I absolutely get why. Nemesis is easily one of the best executed villains in horror gaming. He's nearly unstoppable and, while he does show up at certain set moments in the game, he can also appear at random. With Nemesis around you can never let your guard down."
