Well I thought they really scraped the bottom of the barrel and went right through the the Earths crust when they announced a movie adaptation of 'Where the Wild things are'. It seems that if you right a book, no matter how slight, it will be made into a movie. Same with any comic book or Tv show or game.... ANYTHING but come up with original ideas. I'm still shaking my head that they bothered with a Mummy 3 to be honest, like anyone still gave a shit by then.
At the risk of sounding conceeded I feel the need to say that coming up with ideas is not hard and some really great talented directors out there can make something truly fantastic if they put their minds to it. Hell I like to think I can come up with good ideas, I'm a writer after all.
Incidentally I would recommend hitting the cinemas that aren't mainstream like lets say you live in Perth go to the Lunar of Cinema Paradiso as they play some great independant films. The best ones being anything under the brand of 'Madman studios'.
