Among the five series ABC this week said it would pick up is a new version of “Cupid,” a series that died after 15 episodes in 1998, the Washington Post’s TV Column notes. Another new ABC drama, “Castle,” is about a mystery novelist whose books are being used as inspiration by a real murderer. Among the characters is the novelist’s ex-wife, prompting columnist Lisa De Moraes to ask: “Do you know how wealthy I would be if I got a buck for every time someone in the TV industry wrote a long-suffering ex-wife into their series? If the Alliance of Motion Picture and Television Producers can force Hollywood writers to take squat in online residuals, why can’t it force Hollywood writers to stop putting their own private divorce hells into their latest TV projects?”
