There’s nowt wrong with either Sarah Connor Chronicles or Burn Notice. I particularly like the bitchy dialogue between Michael and Fiona, plus Gabriel Anwar is a seriously fit bird! Can’t say I’ve noticed any change in her accent, but for heaven’s sake, people living in other countries take on some of the local accent after a while, and there are aspects of Irish in the American accent anyway. FWIW, Gabby Anwar is actually English, she’s from Middlesex. Sarah Connor Chronicles also has the utterly devine Summer Glau, for which I would happily forgive any faults in the programme, but it wee’s in Heroes and Lost’s shoes,
IMHO.
