What are you waiting for? It's on I-player, turn it on now! You won't mind watching it again with your husband.
I have to be very careful about not letting him know I've seen something if I want him to see it. While he was working in Salisbury, I watched the entire 4 series of Halt and Catch Fire. He had tried to get him interested, but he seemed really disinterested in it, so I watched them. A year later, he suggested it, I said I'd gone ahead and watched them but I'd watch again because it was that good. He thinks maybe in a few more years, when I've forgotten everything, we can watch it. And I've never spoiled anything for him, ever! (Oh, except constantly telling him "it has raisins in it... you like raisins," and
then making him watch Better Off Dead.)
Edited to add: iPlayer? Hmph. We don't get to watch iPlayer anymore. I mean, we could if we paid the TV License fee (which I kind of want to do, just to fund the BBC). We might have to wait for Netflix to buy this one in a few years' time.
