Goodnight Sweetheart for me, I often watch it from start to finish.
I really liked the new episode when they were looking at bringing it back. Shame the BBC decided to then bin it.
Aye the one off thing, that wasn't too bad.
Obviously it lost a lot when they had to replace the actresses that played the two wives in series 4 but the idea of the show always kept me interested.
Time travel in most things keeps me interested and the dimension of it being based around the 2nd world war was also an interesting plot.
