yep, I understood it, I liked it. I liked it enough to watch it again.
Before watching it, I forgot another option I had, to tape Torchwood downstairs and watch Frost in my mums room which also has freeview. She was out at the time so I was free to do it...I missed the first 5-10 minutes but there was 2 hours worth there so I caught up with it (well, including brakes
).
