I tried to get into Luther and Top Boy years ago, but I just couldn't get past those accents.I gave up on True Blood after that Vampire/Werewolf war most sorriest display of werewolves I've seen in my life.
As for Shameless a big part of me preferred the BBC british version that, Doctor Who, Luther, Top Boy, Skins, The Inbetweeners and etc were keeping me very entertained
No disrespect to the bruvs, though.
