Overall, I really enjoyed the series. I loved it being a five-parter; it was like a return to the old Doctor Who serials, which is something I've been wanting for DW for a while. I love multi-episode arcs.

Throughout it, particularly after Ianto died, I was expecting there to be a reset button of some kind, or some hitherto unknown way out of it, but I was kind of glad there wasn't. The last episode was dark in a way that I hadn't expected, and though it gives me a perculiar feeling, I'm glad they did that.

Jack has a lot of redemption to go to make up for it though, a lot of soul searching to do before he can come to terms with it. If they bring him back in either series without addressing that, I will be mightily annoyed.
