The edit removes most obvious flaws in the PJ's version of the LOTR story. Among them are:

1. Osgiliath "detour" - not true to Faramir's character, with his Numenorian spirit.
2. Aragorn's fall - not respectful to Aragorn's character.
3. Arwen leaving - not true to Aragorn's and Arwen's love and characters. Not true to Elrond's character. Ignores the traditional view on Elf-human love (that goes back to Beren and Lutiel).
4. "Gimli the clown" - not true to Gimli's character. He is a prince, for Eru's sake.
5. Ent's indecision - not true to Ent's characters.
6. Theoden's "exorcism" - not true to the magic traditions of Tolkien's Middle-Earth. Not true to Gandalf's character (who is not a "conjurer of cheap tricks").
7. Elves at Helm's Deep - not true to the heroism of Rohan defenders. Not true to the strategic picture of the War.

Many of these changes by PJ were also done in a cheap populist way, targeted at the mass audience with its primitive taste.

The edit used the theatrical version (promo-DVD, the only available version at that time), it doesn't incorporate additional footage. Audio transitions were done properly to smooth the cuts. Music from the soundtrack and the trailers was used.
