Joss Whedon, creator of such TV cult favorites as “Buffy the Vampire Slayer” and “Firefly,” discusses Twilight in a new interview.

TVWeek: Vampires are big in pop culture right now. Have you seen “Twilight’?

Mr. Whedon: I saw “Twilight.” And it’s—what can you say? It’s absolutely like crack. It strikes a tweener chord that’s just as loud as the apocalypse. You cannot deny the power of it. It just works. And I sort of like that.

TVWeek: What about HBO’s “True Blood”?

Mr. Whedon: I’ve seen less of it. “Twilight” makes its own rules, as we all do. It takes what it wants and discards the rest but ultimately, it is kind of classical. They’re puffy-shirt vampires in a sense.
