I've been watching it on Talking Pictures, all episodes from series 1, and although I'm old enough I can't remember it first time around, but I'm completely hooked!!
I'm about half way through series 3 and can't wait to get to the end.
Brilliant series, extremely well written and acted.
You can see the connection with Allo! Allo! and Secret Army is obviously where they got the idea from but it doesn't spoil either show for me, I'm also a huge fan of the comedy version.
