The new TV Guide talks about the show's cancellation with Liotta saying he thought it was a disservice for the network not to give the show extra time to breathe and build. However, he also says the producers share some blame as even the cast didn't know where the complicated story was heading and that wasn't a good thing to make the network feel easy. He thought it would have been better to have the tension between Bobby and Hope be more promiment in the early episodes.
Have to admit, he raises a good point on the story being too complicated and the network should have given it more time. Still, when ratings are poor and the budget is roughly $3 million an episode, networks do panic.
