lakritze,

One problem that arises from this approach is, as Steph observed above, that it is at variance with how the word is commonly used in English.

Rather than use the word “bias”, which has negative connotations, I’d suggest “point of view”. Mr. Moore is entitled to his point of view, and is also free to express it. He seems to be more than a little ambiguous in regards his film, as he had no problem accepting an award for it as a documentary, yet, as Steph comments, states that his point of view comes through.

Given these realities, wouldn’t “Editorial” or “Opinion Piece” be a more accurate description of his film? Surely being honest about what he is presenting would serve to emphasise the difference between his efforts and those of his subject, about which he expresses grave reservations?
