I think this series of Dr Who plays a lot with the whole man/woman male/female thing, but so far even in my heightened state of wariness for 'fashionable' viewpoints, I have been ok with most of it.
It has been the aliens who have the male/female switch, the humans seem to remain definitely - and happily - bimodal.
(derail) But in the last episode (the one with Chris Noth), I couldn't help but notice that when the Doctor shouted something like "don't kill the alien monster" at the threatening alpha male, SHE was not getting through as well as even Tennant would have.
A woman shouting at a male just came across as not authoritative.
I don't know if it's just the relative screen presence of the actress and Chris Noth, or if it was an intended dig at human socialisation by the writers.
