The cast of the show was pretty well chosen, everyone seemed to fit their parts well, those not familiar with the source material might balk at the stereotypical sometimes even racist depictions of some of the characters, but its all to a point. The original film much like this show wouldn't win any major awards but at the same time it shouldn't be fed to the pigs like many other "tv series" adaptations.
the first thing you notice about this is whats missing, like the lack of the characters "Turkish, Gorgeous George, Tommy (and his sausages that even by the end of the movie still aren't cooked)" and Alan Fords "Bricktop" however key points being the main bit of the story, the main character loses loads of money in a rigged fight he was trying to win with his boxer, coming upon a large fortune that everyone's interested in, and of course the pikeys.
id call this a decent adaptation but really hope that we see something more of it, at only 10 episodes and a lot of the source left untouched, there's plenty for a second season to hopefully make a better impression. especially if they bring Alan Ford into the mix,
