I am obsessed with this period drama set in Birmingham during the Victorian times. I think it's so clever, and so well-done with all the small details in their set design and the costume design. The gangster family that rules and protects over Birmingham returns for their fourth season, although I'm sure it could continue, and I'm hoping it will continue for many many more seasons. This particular series is so full of drama and one of my favourite seasons since I think the characters really develop and there's a definite divide within the family. This seasons premise is that Tommy, the main character, had previously killed an Italian mob member in one of the earlier seasons. The Italian mob then comes to Birmingham to try and get revenge for his death, resulting in a war between the two gangs.
