I thought Donna was fine, and Ten had some very nicely Ten-like turns of phrase, culminating in a bit of Doctor bad-assery, which is always nice. And I liked that he was mainly concerned about what might happen to the poor native folk for being unfortunate enough to have this technology that they shouldn't have and maybe attracting unwanted attention. And I liked that you stressed their non-violence too instead of making them into a typical load of nutty cultists. Well, bring on the next part, then!
