And so is the rest of the cast - this is gritty British TV at its very best. If you don't like gritty and dark, this is not for you - it's no Midsumer Murders. It also shows a Britain that most people outside of it usually don't get to see or even know about. Another interesting aspect is the fact that this is set in LIverpool and most of the cast speak with a (more or less pronounced) Scouser accent. Britain is such a diverse place, but most people only think of London and the South when they think of it. I've always liked Martin Freeman, but I had no idea he was THAT good of an actor. He's incredible in this, and the young troublemakers (the junkie girl and the dim wit dude, I can't recall their names now - oh hold on, Casey is the girl).
So anyway, to make a long story short, this should be rated way better than a 7.4 on here (Rotten Tomatoes has it rated much higher!) and I highly recommend it!! Hopefully, there will be a Season 2!!!!
