WB boss explains reason for Angel cancellation.

Jordan Levin, the network chief who axed Angel, has been explaining the reason for his highly unpopular decision.

"The big problem with Angel is it didn't repeat well," Levin told E!Online's Kristin. "It wasn't growing its audience, but it was a show we loved. We adored that show. It was a really hard decision.

"Joss Whedon came to me in February and said, 'If you don't think the show is going to come back, I'd rather know it now, so I can end it appropriately.'

"When we looked at our schedule, with Charmed, 7th Heaven, Gilmore Girls, Angel and Smallville, we realised we had a lot of veteran series. And one of the challenges of any schedule is to let your veterans retire so you can make room for the rookies, like Jack and Bobby and The Mountain. It's a balancing act, and it's not fun. That was a sad day."
