The extended cut is no extended cut. The director lied saying the film would be longer and more exciting. That's false advertising right there and he was the wrong choice to direct this film. Don't bother buying the extended cut because it's still less than two hours no matter what the box says.
i saw the movie in the theater and i just watched the extended cut earlier this week, they traded out all the stuff with his daughter for stuff that didn't help the movie. if you want the blu rays, and you don't have the others on blu ray, wal mart has a box set with all 5 movies on blu ray, the blu ray for this movie is the theatrical cut, which is just as good or maybe even better than the extended cut. i really don't see how it is extended when they just cut stuff out.
