Channel 4 are really doing a great job of advertising a show that would be fundamentally ruined by spoilers. Or worse, ruined by suggesting connections between certain characters and pieces of dialogue taken out of context. Instead the tv spots do nothing but raise further questions, which is perfect.
Not to mention, more Arby. Always happy for more Arby.
Edit: There is now nothing scarier on this Earth than a bright yellow, leather hold-all.
