Good for you, Trav. Making a parenting decision and not letting a government agency make it for you! (And I agree, Return to Oz was far scarier than Terminator - I wouldn't even read the Oz book until a few years ago, the Wheelies scared me that much!)

FWIW, I won't let Liebling watch Potter. He has played the Lego computer games and loves pretending to be Harry and Bellatrix and the like, but he cannot watch the films until he has read the books. It does annoy me that superhero films are all highly rated these days: while my 5yo would love to watch Spidey and Batman, it just ain't happening yet.
