People have said this show is not very good but perhaps they are looking at it the wrong way.
It's a bit of a throwback of a show to simpler times but that doesn't mean it's any less engaging. It's easy to watch, you don't have to know a lot, the writing great with some excellent and funny banter between cast members and the cast is excellent.
The best thing is that in just a few short episodes, you get involved in the character's lives, even if they are relatively superficial glimpses of people with complex issues. They are minor criminals but in this show, they still warm your heart to some degree. It just works.
Christopher Walken adds a really great dimension to the whole thing. Excellent casting and it was great they were able to get him on board.
I wondered when he was going to start dancing. He was originally a dancer so his movies and parts always includes one or more scenes where that happens. I was not disappointed.
There has to be second series. If there isn't, I'd be surprised.
If Walken doesn't turn up again, be interesting to see David Soul back on the small screen doing a turn.
