They are just painfully, totally, CRAPPILY UN-FUNNY, usually revolving around some dysfunctional family and re-hashing the same stereotypical gags. Will Mellor irritates me just by sight - can he only play one character?! I can't actually think of any really funny recent ones. My mum loves My Family, but I never "got" it.
Just annoyed cos this dross is wasting half an hour between Waterloo Rd and the Apprentice...
Give me the oldies - Only Fools / Fawlty Towers, etc any time!
