It's honestly shocking that they pulled the plug on this one.
In her People interview, Gellar singled out one executive. “We had an executive on our show who was not only not a fan of the original, but was proud to constantly remind us that he had never seen the entirety of the series and how it wasn’t for him,” she said. “That’s very hard when you’re taking a property that is as beloved as Buffy, not just to the world, but to me and Chloé. So that tells you the uphill battle that we had been fighting since day one, when your executive is literally proud to tell you that he didn’t watch it.”
Gellar did not name the person; according to multiple sources, the executive Gellar was referring to is [Craig] Erwich.
This seems like a tale as old as time, though.
