Little brittan didn't impress me at all, and still I'm a big Brit-humor fan.
Little Brittan is just to obscene, flat, tasteless IMHO. Seems it's easier to go that way than to come up with some really silly stuff.
Luckely, "Have I got news for you", Jeremy Clarckson, Coupling and many other presenters/shows proove that British sillyness is still out there...
