I think it was not only brave to try something different, but clever too. I still find myself thinking about it now. With some dramas I've watched, they soon go out of my head. Great actors too.
You're not gonna believe this, Tilly, but i switched iplayer on, selected episode 4, pressed 'start', then FF'd to the credits and pressed the 'pause' button. :-))
By the way, i'm glad i did because when i watched it first time round, i switched off as the credits rolled and missed the actual final scene. Having read it mentioned on here a few days back, i watched the last few minutes on iplayer today.
