Both of these statements might together, I think, explain why I am disssatisfied with the movies as movies. PJ's imagination is watered by two sources: Tolkien and Lucas. Yet rather than out of this creative ferment producing new vintage wine, he produces some vinegar.
Take, for example, the skateboarding scene in Helm's Deep. Or the dwarf tossing comment. In
Star Wars that kind of bragadocchio reflects upon the characters. Han Solo's "That's great kid. Now, don't get cocky" works as a humorous interjection into the battle because it says something about both Han's and Luke's characters. The line reads like the effort of those fighting to lessen the impact and force of ... The Force, if you will. It is part of their battle strategy. At Helm's Deep, the skateboarding and dwarf tossing are mere additions for the sake of humour. And both the tragedy of the battle and the dignity of the characters are lost.
The same thing when Aragorn's horse nuzzles him awake from the dream of Arwen. Haha, sure, funny, but how does that develop Aragorn's character or depict this supposedly iconic love and romance? It doesn't. It is just a but of cheap humour thrown in.
Similarly, for me, is Gandalf's arrival atop Shadowtax and the great rearing shot of the horse. Roy Rogers to the rescue? The cowboy motif fits Han Solo because that is how he is presented throughout the ST trilogy: he is a gunslinger in space. But Gandalf is not. He has, from the beginning, been a wizard and interjecting a cowboy image late in the game takes artistic skill which the director does not have.
This discussion could turn into a version of the Canonicity argument: the Director, the film, the audience, but I don't think it is so much a question of 'dumbing down' for the audience. Rather, I think it is a question, as
Mr. Underhill suggests, of PJ's nature as a filmmaker. This is his interpretation of how to bring Tolkien to the screen. Yet he fails to appreciate the mythic or moral stature of LotR and his fails to understand how Lucas uses humour in ST. Thus, we have diminished charactertisations and misplaced comedy and changes which don't ring true as a movie.
Knights in battle have a different tone than cowboys in space. PJ could not amalgamate the two into a unified, coherent filmic vision. Too many semes show. (And, yes, I do mean 'semes' )
