Although it's not the best drama ITV have ever proffered I'm thoroughly enjoying it and looking forward to episode 4 tonight. It's gritty, and the gruelling struggle of the working class underdog juxtaposed with London's wealthy elite makes for engaging viewing. The show has a good pace, mounting tension and a funny, relatable and watchable lead played superbly by Sheridan Smith. Im surprised to see so many unfavourable reviews!
