Series 4, finale (power station, yokels, radiation, heroics)
This review http://www.theartsdesk.com/tv/endeavour-series-4-finale-itv sums up most of my reactions to last night's episode.
It was a slightly curious evolution of the Morse canon. A preview did suggest "Morse does Wicker Man", but the uncommunicative villagers, the scarecrow (I did wonder if it concealed human remains) and the Morris Men served to remind me of "Midsomer Murders" (filmed only a few miles away from Oxford).
Obviously the scriptwriters have to invent a life for young Endeavour, but I can't recall there being any reference in "Morse" to his being awarded a George Medal. And in the new series it's no secret what his first name is, whereas the Thaw Morse kept that very quiet.
But all in all a very enjoyable episode and series.
I wonder where the power station scenes were filmed: Culham? Harwell? (I think the distant views of the station may have CGI) And where is the very picturesque village?
