To watch this show in binge fashion it will take just short of four and a half hours, but it is well worth it. No use giving up after 10 minutes as most of the reviewers have done and writing a bad review just because you didn't like one or other of the actors.
The story line is familiar with other shows, but that doesn't matter, it is still good entertainment. It may be a bit PC, but who cares it is still entertaining.
Having seen many of Paul Abbott's shows this might not be up with the best of them like Shameless and No Offense, which are brilliant, but it compares quite well.
Definitely worth a 7.5-8/10 and I would highly recommend it if you are looking for something interesting to watch.
