I've not seen Ruddy Hell, the new thing with Harry Enfield and Paul Whitehouse but the general consensus is that it is rubbish and in bad taste.
Is it me or were a lot of these comics better when they did not resort to toilet humour etc?. For example the first series of Harry Enfield in the early 90s was funny because he based a lot of the characters on real life. When he started resorting to smuttier humour the comedy just was not there. I think the same could be said of Little Britain.
I like smutty humour if the jokes are well written - usually done by stand up comedians. The same cannot, in my opinion, be said for sketch shows.
its like a lot of comedy shows - enjoyable for half an hour, but forgettable. you don't set the video for the next episode but will watch and enjoy it in passing.
this will not be a classic or spawn a plethora of new catchphrases.
to be fair to them, they are considered comedy giants so it must be extremely difficult to top what they have done before - they will always be compared.
