In reply to The Lemming:
I think it was the second series that was broadcast directly after the BBC's adaptation of Gormenghast. For all that the latter was supposedly a dark, gothic fantasy*, I thought the League of Gentlemen was much darker; plus it had laughs too.
League of Gentlemen 1, Mervyn Peake 0.

* I read the books (some time ago, admittedly) and thought them dreadful; not dreadful in a dark gothic way, but in an utterly kind of way.
