Despite being expected to return for a third season, it was announced earlier this year that the sitcom had been cancelled due to budget tightening.
Speaking to Entertainment Weekly, executive producer Donald Todd said that the cast and crew cannot understand the reasons behind ABC's move.
"Sadly, ABC's strategy to get new viewers - by taking the show off the air for months at a time - did not pan out, and they have no further plans for us," he said.
"The producers, and Christina, remain baffled by the whole thing. As viewers can see in the final episodes airing now, we were heading in a great direction; the calls and e-mails about those episodes are both gratifying and painful."
