What a shock! Was told to expect it, but even so! A definite ending tho.
What bugged me though was Tyler deciding to "go back to 1973" and taking such a drastic route to do so. What was also sad was the Test Card girl appearing at the very end, as if she was symbolising Sam's death. I'm inclined to believe that although apparently the makers of the programme don't. As for feeling alive, as much as any decent person would adore DC Cartwright platonically or romantically, doesn't feeling alive come through struggle to come to grips with the situation you are in, not simply down to positive feelings?
Ah well. Cracking series though, miss it already.
