if you ignore the fact that the story is very different to the book sometimes, the movies are worth seeing, and I think if you liked the former movies, get this one, too. there are already very cheap offers, if you don't want to spend too much money on it.
However, you have to forgive a few changed scenes (the one that is most difficult to forgive is when Frodo sends Sam away. I don't know why PJ did that...)
But the when I watched the extended after I bought it, I thought, "now there's nothing missing!"
Ah, so PJ did include the scenes of the wedding night of Aragorn and Arwen, not to mention the wedding night of Legolas and Gimli ?
Maybe it's worth buying after all then..
There is a page that shows all the new scenes in the extended edition, if you want to do more research -
DVD File .com : The Return of the King Extended Edition Review
It is absoluyley wonderful as it not only has BRAND NEW scenes, but also EXTENDED versions of scenes that were already there...which is great!
And it really cleared up stuff for like, my mom and dad...they understood some of the stuff a lot better.
I CLEVERLY asked for all three of the extended versions for different birthdays and Christmas's. Therefore...those versions are MINE AND MINE ALONE!!! (insert evil laugh here)
But no, it's is definetly worth getting.
Oh and I'm have a dumb moment. Refresh my memory...which was the Mouth of Sauron scene?
At least one cannot argue that the once and future King did not have taste!
