A nice introduction to this spin-off which, I'll admit, I knew nothing about. I'd heard about Liz having a wife somewhere ages ago but I didn't know anything stemmed from this! So, I loved the cast, they were really on fine form in this. I love Liz as a companion a lot so this is right up my street as Cheryl Cole would say. The last 10/15 minutes lost me a little I'll admit, but the plot itself was really quite good, mysterious and surprisingly very tonally dark compared to Doctor Who! The end intrigued me a lot, as I expected this series to be a monster of the week kind of situation, but it appears not to be. Excited to continue and learn more about this obscure corner of the Whoniverse.
