For me a lot of the more modern comedies and comedians are just trying to be vulgar for the sake of it, possibly to hit headlines etc.
I am probably more into the older comedies and comedians than the new ones, ith thed likes of Dave allen,Ronnie Barker and Billy Connolly being among my comedy heroes, I also collect a lot of the older sitcoms from the 70s and 80s which I grew up with

Modern stand up comedians that I do think are Ok,
Lee Evans,Lee Hurst, Stephen K Amos,Micky Flanagan,Sarah Millican, Lee Mack and Tim Vine(at times),John Bishop, Al Murray is a pretty good character more a modern day Alf Garnett in a way.

Modern sitcoms I like are
Not going out,Miranda and Outnumbered. All of which really follow older style of sitcoms really.
Ricky Gervias just really annoys me he is unfunny and big headed in my view,Peter kaye is too repetive although was very funny at first.
Little Britain was just too much of the same thing and for me less funny than it ever got rated.

I am not against swearing etc, what I do have an issue is when its just for the sake of it, Also things like people being sick or other body function just is not amusing at all let alone after the 20th time.

I guess really though We all need a laugh every now and then after all life is hard and laughter just make things better for a bit, So I figure if it makes you laugh and does not hurt anyone else then what the hell, keep smiling.
