I even find some use in new buzzwords now and then as they refresh the focus and increase motivation. If you take them for what they are they are not even this annoying anymore. Gurus are annoying tho albeit there is an entertaining value there too. From all the gurus I find the ones mumbling about agile & water fall the most entertaining - I never know what the outcome of the proceeds would be. I laugh every time I see a workshop in which some management consultant is attempting to fix problems of others but cannot get around to organize own workshops in such a way as to make at least one person leave them with added value besides entertainment.
As for movies I liked Starship Troopers with their fascist social structure etc - you could see what properly done PR campaign can do and that sometimes throwing more people at it is just as good waste of resources as anything else
