Is it worth watching? I didn't watch past series 1 because my wife found it too upsetting, but said she might want to watch it in the future. Given they're now filming series 5, I might watch it without her, but if it's only mediocre, I won't bother.
It's been good throughout, last series or two had a different focus and maybe dipped in the middle because there was less constant, horrific tension but finished strong.
