http://www.youtube.com/watch?v=XjPb3ziyYYo More proof that throwing time travel logic into an established franchise is a horrible idea, Harry Potter and the Prisoner of Azkaban creates a problem that permeates throughout the rest of the series when Harry uses a time-travel necklace to go back in time and save both himself and his godfather from the dreaded Dementors. The first issue is that the film, like so many, treats time travel with a needless urgency just to make the plot feel that more exciting, when in actual fact, the whole benefit of time travel is that it gives you boundless freedom to do what you want when you want. Mere possession of the device is enough; if you screw up, you get a do-over. What's more frustrating to me is that the time travel device is only used once throughout the entire series, which seems pretty ridiculous given how many people die in the later installments in the series. Wouldn't it make sense to use a necklace to save some of those lives? This is why writers must think long and hard about introducing time travel, and Rowling clearly didn't.
