Baloney. For one thing, with the TT you have a ton of solid, direct story. You're complaining about appendix material and minutiae that, put together, wouldn't make a season of a show, let alone a show.
Also, the changes in TT were not minor. "Men stand alone at Helm's Deep....nah, but the elveses are cool, we'd better include them." "Faromir will refuse to let the ring influence him....no, actually, he decides to drag them and the ring along with him." And so on.
There's a very verbal minority that hates on RoP, and they can go on doing so without care from me. And I'm the guy that always criticizes adaptations!
