i don't disagree with your premise, i just think you should pick someone more deserving of the defense. i mean, i grew up watching moonlighting, the die hards, i even enjoyed hudson hawk... and whether it's due to early onset dementia (or some other issue beyond his control) or that he's phoning it in, the fact remains he's not pushing out the same quality of content that he was 20 years ago.
i mean, he's gone on record saying that his fee is something like $1 million per day, and if they can't pay him that he'll find a studio that will. that's why his movies all suck now and it explains being fed lines and his odd affect while saying those lines. when he says those lines, he probably JUST heard them for the first time. the director's job isn't really to make a good movie, it's to manage the day or two that they could afford willis so that they get as many shots, and as many lines of dialogue that they can possibly get.
