I'm not sure how Fox is to blame. If poeople don't watch then they don't watch.
In case anyone was assuming that the major changes in writing and focus are the reason why ratings fell below 5 share in Season 2 ... ratings inexplicably rose for the last 3 episodes of the season, from 7.75 to 9.22 million to 8.13 million viewers for the finale. I'm sure the executives are scratching their heads about that one.
