There is nothing more amusing than when two people known for being non-objective argue over objectivity. This is the summation of Keith Olbermann vs. Ted Koppell.

No two people who make a movie on a certain budget scale are going to achieve the same thing because it just depends on what sort of favors you can call, and what sort of dynamics you can pull in the play.
Just as two people can have similar personalities, two companies can have a remarkably similar approach to business.
I think competitiveness between two people is still relevant, and the battle of the sexes still intrigues.
