If you've seen Sean Lock on any of the British panel shows, (8 Out of 10 Cats, QI, Argumental, TV Heaven, Telly Hell, etc.) you'll know he's a little cynical, but in the best possible way. He basically says out loud what most of us are only thinking. And it's genius.
In 15 Storeys High, he takes this cynicism to another level. Playing the fictional "Vince", Lock is sarcastic, opinionated, bossy, but delivers with the dry nonchalance that I love about British comedy.
I'd watch Sean Lock in anything, but this show is truly good.
