OMG!!!! I'm a huge Idris Elba fan , I don't know why I waited so long to tune in , but when I did i couldn't stop watching . Everything around me went black and I was drawn to the show. Alice Morgan and John Luther are the perfect duo. I cried when Justin died , this show has really grabbed me and sucked me in. Just finishing season 4 and anxious and anticipating season 5 , I just know Alice Morgan return is going to be grand. Thank you BBC for this show .
