I disagree with their notion that TDK "ruined" the villains. What has been the issue that most of these comic book movies don't give a damn about the villain and toss them in as an afterthought or a counterbalance to the hero instead of making the villains into compelling characters on their own.
That is why The Joker worked so well in TDK, he was a fully formed character that Nolan/Goyer/Ledger put a lot of thought and care into crafting.
Its the same reason why Loki has been the only Marvel villain that isn't mediocre.
Its why both versions of Magneto (Fassbender and McKellan) have been so well received.
Its why (despite how much as people bytch and moan about his casting) I felt that Jesse Eisenberg was a successful Lex Luthor. There was time and care put into the creation of that character on the part of everyone involved in BvS. Same goes for Michael Shannon's Zod in Man of Steel.
Also breh, thats what the article said. Did you read it? You gave his thesis statement and he went on to explain why no one has reached quite that level (at least for him)
