“Crusoe” is, thankfully, the last of its fall scripted series. That is, unless NBC has some other surprise bomb to drop. Here’s the dreadful tally of new NBC shows so far: “Knight Rider” (brutally bad), “Kath & Kim” (heinous), “My Own Worst Enemy” (yes, it is), “Crusoe” (insipid). By the way, three of those four are borrowed ideas: “Knight Rider” resuscitates the lame 1980s original, “Kath & Kim” ruins an excellent Australian series, and “Crusoe” does no justice to Daniel Defoe’s book. (More on that shortly.) And, really, “My Own Worst Enemy” is just a terribly muddied version of “Dr. Jekyll and Mr. Hyde.”
