I disagree big time, and you are part of the vocal minority. I lie all the characters and they play their roles real well. While D is your typical brooding, stoic-is-cool/badass, it's not played to an obnoxious, absurd degree, unlike Sasuke Uchia. Whatever moments of sympathy or vulnerability do come from D, makes it all the more powerful and adds something to him. And this would not work with out Lefty, his left hand infected with a parasite who is a comical riot. D plays the straight man to Lefty's sarcasm and smart talk. Their reason why the novels tend to focus more on the characters around D, than D himself. You still see it in Bloodlust, but more is done to balance the characters out. D ain't no Alucard (Both of them. Castlevania Netflix & Hellsing ), Blade, Integra, Seras Victoria, Kagura (who is stripperific Dante), or Saya but I like the guy. I love the dynamic between D, The Marcus Bros, and Leila. Meierlink has the woe is me vampire going on, but surprisingly works and is not insufferable, and I can sympathize with him and Charlotte just fine. It was love story written and done better than Twilight and Vampire Knight. I actually teared up a little. Something rare for anime about vampires can do to me. I recommend you give the film another shot, but I highly doubt you're gonna do that.
