My brother in law and I love it. It's excellent IMO, gets a lot better as it goes also.
Ayoade is one of the funnier guys in a while, and the stuff he does on Britain game/quiz shows are brilliant, kind of sad he hasn't caught on here like a Russel Brand has for example (though Russel Brand is good as well, but Ayoade is in a different way)
As far as British TV in recent years (if we want to call IT recent) I'd put it only behind Misfits, though Misfits is Comedy/Drama/Sci Fi so it has easier appeal.
