I've watched all of the extended material of all three movies where Philipa, Jackson and the actors try to defend some of the changes, but none of them really give any good reasons.
Than watch them again.
They explained themselves quite plainly, and quite convincingly.
How 'bout these for starters?
* Building up the One Ring as the biggest threat EVER (even one that demigods are terrified of facing), and then having a simple man (Faramir) walk up and not be affected at all by the pull/promise of the Ring does
objectively weaken the threat they worked so hard to build.
* Having Frodo and Sam be simply by-standers at the conclusion of this epic journey, while Gollum beats them, takes the Ring, then luckily (for all the Good Guys) slips and falls into the lava thereby succeeding in their quest is a much worse ending than having them be active participants.
Their decision to re-write and re-shoot that scene is critical to acheiving a satisfactory conclusion to the quest. The version they decided upon also has the benrfit of further reinforcing the pull of the Ring (Frodo fighting Gollum for possession, dragging them both over, instead of him pushing Gollum off or Gollum falling off).
Those are darn good reason, and quite plain to see, if you are not using the book events as a straitjacket.
BTW:
I don't know if this has been mentioned, but there's another MTV Movie Awards Easter Egg in the same place on the RotK EE: Go to the last scene (Fan Credits), and press Down.
