I remember liking the Hurt era because of how grimdark it was. But I was only 18 when it started so I didn't really know better. It definitely was aping BSG, especially in the last two seasons.
I don't think The Doctor really needed to flush that Sontaran out the airlock in "Ghosts of Pyrrha".
I will say, the episode with Peri as the Queen of Rathagon VI is in my top 10 Who episodes of all time. And not because of the nip-slip.
