Jane Espenson explains decision to step down

Jane Espenson commented on the change of showrunner to io9.com:

I'm still at Caprica. Running the room was very intensive and took a lot of time away from actually writing this amazing ambitious show. I missed the writing more than I expected and this was my decision to concentrate on that as we put together the big end of season one. Kevin is extremely smart and talented and brings fresh eyes and fresh energy to the project — we're so lucky to have him!
