Perfectly okay story, not super memorable. Nice Charley moments, especially her being pissed that Doctor is going to nobly offer himself up as a sacrifice out of guilt, which would leave her in 1)outer space 2)in the future 3)with people she's just met. The Doctor's mistake with lighting up the artificial suns ends up not being a mistake in the end, which felt like cop out, plotwise. And the Cimmerians were pretty chill about it anyways; the Doctor is like 'I'm ready for punishment :(' and they are 'oh, no, it's okay man, we all make mistakes :)'. Overall, the beginning of the story was great and scary (big fan of the Cimmerian's little whisper-y voices), but it got boring the longer it went on. ROSM was nice! The others were meh.
