I'd agree with that company parting, if it is such, although the degree of dilution from the original can possibly be seen in one word: Troy. (Which did, on the other hand, give us some fantastic spork!) Oh, and possibly that's another indication of the new Steepholmic theory's limits? In that a film version insufficiently close to our pre-existing mental vision, will be dismissed out of hand or just enjoyed for its cheesiness. As, frex, the Kiera Knightly P&P with the 'You have bewitched me, body and soul' rubbish? Although there is that handy 'can' in your final sentence.
