Mark Sheppard is brilliant in everything I’ve seen him do, but as Crowley, the usurping king of hell, he has an awesome Brit-stereotype camp to his demon. You know he wouldn’t think twice about sacrificing anything to save himself, but he’d do it without getting his hands dirty. At the very most, he’ll straighten his tie after decapitating an adversary. He comes across as totally omnisexual but you suspect he secretly could never love anyone more than he loves himself. (But if flirting with a man will make said man uncomfortable, he’s more than happy to do it.) And his rebooted version of hell – the eternal queue – is perfect. I just hope we haven’t seen the last of him.
