I have just read an article on yahoo - they are making a new film about the Teenage Mutant Ninja Turtles, which I adored as a young lad. Bizarrely, they are changing their entire reason for existing from pet turtles who came into contact with toxic waste to them being aliens. A huge storyline shift for no apparent reason. It makes you wonder why you would buy up a franchise just to change fundamental aspects. Anyway, aside from now vowing never to see the film, are there any seemingly pointless, yet massive, plot changes that have really got on your wick when you've gone to see a film?
