It just takes a while sometimes for me to convince OH to watch stuff. Thankfully the Wire set a precedent. After I'd watched most of the first series the first time it was on:
OH: This is boring cr*p. I don't think we should watch it.
Me (relunctantly): Ok.
[Zoom forward until everyone is raving about series 5]
OH: we need to get the box set of the Wire. Everyone is going nuts about it at work
Me: I watched most of the first series and then you said it was boring cr*p and I stopped so no I'm not buying the box set.
So far I've used "You said that about the Wire and then wanted the box set. Give it time" for Game of Thrones, Breaking Bad, Banshee, Madam Secretary, Stalker, Falling Skies (which starts again tonight btw), Prison Break, Walking Dead. I do think I've failed with Humans and The Interceptor though, I have to record those.
She does like cycling though apart from TTs and TTTs which is fair enough cos I can live without those.
