Mike Ausiello believes the bigger news about 90210 full season pick-up was the announcement of the new show runner, who has strong Gilmore Girls ties:
“In the final sentence of the bulletin, the network quietly mentions that veteran Gilmore Girls scribe Rebecca Kirshner is joining the series as an executive producer.
And it gets better.
After I did some digging, a 90210 source confirms to me exclusively that Amy Sherman-Palladino’s longtime collaborator will not just be sitting in the show’s writers room, she’ll be running it. (And yes, contrary to speculation, the show does have one of those.) Gabe Sachs and Jeff Judah, meanwhile, will continue to serve as show’s day-to-day showrunners.”
