This Doctor Who spinoff has been called "adult sci-fi." Adult, probably due to language, adult situations, and brief (comical) male nudity.
The episodes were generally well written, and I had to resist the urge to binge watch. It was like a book that one couldn't put down. There are many interesting extras and commentary on every episode.
The transfer is 1080i instead of 1080p. A reviewer on another site said that it caused problems with his Blu-ray player and that it was a known problem with BBC Blu-rays, including Dr. Who until Series 7. This set played fine on my Sony E2100 home theater Blu-ray.
Some minor complaints:
-The deleted scenes are not always on the same disc as the episode.
-Sometimes the same interview appears in different extras.
-The menu doesn't have episode selection. One has to use scene selection, choose the episode and then choose the first scene. Also lacking was “Play All.”
-For some reason, in every BBC set that I buy in a slipcase, the binder with the discs has worn corners and a crushed spine, even though the slipcase is fine. It makes the set look used.
This set isn't worth the MSRP of $89.99 (no 13 episode set is), but Best Buy sometimes has it on sale. I plan to grab Season 2 at the next sale. In the meantime, I want to watch this set again with the commentaries on. It was that good.
