David Greenwalt, former executive producer of UPN's Buffy the Vampire Slayer, told SCI FI Wire that he's sorry to see the show conclude its run, but added that he thinks it's better to pull the plug now than wait until after the series has grown stale. "I think it is time for the show to end," Greenwalt said in an interview.

Greenwalt added, "Seven years is a great run by any standard. [Creator] Joss [Whedon] never likes anything to get stale." He said that there may still be stories to tell. "Have they done everything they could do on Buffy?" he asked. "No, because it's such a fertile idea. I would hope to see some Buffy movies. But I do think seven years is terrific. Get out while you're still good."

Greenwalt has moved on and is now executive producer of ABC's Miracles and remains a consultant on The WB's Buffy spinoff series, Angel, which Greenwalt co-created with Whedon. Naturally, he knows what's in store for the Scooby Gang. "What they have [planned] for the finale is so extraordinary," he said. "It's like the size of The Lord of the Rings, in terms of the bigness of the battle. It's just great. It will pull out all the stops." Buffy airs Tuesdays at 8 p.m. ET/PT.
