If you've not started this yet, and not watched the film, I'd suggest watch the film. When I heard they were making a show I thought leave it out. I watched the trailer for the show and thought OK, I'll give it go. I must say it's pretty damn good, it's so much fun and a right laugh. I love the characters, and as other reviewers have said Gal and Don are excellent. In the film you get 'the full fat' version of Don, in this he's a kind of skinny latte version, but giggle so much knowing what he becomes. Tamsin Greig who plays Cecilia is another stand out, her character is wonderful, I love her and she loves dropping the C Bomb. Personally all the characters are fun and it's a show, like Slow Horses that doesn't take itself too seriously. I'm thoroughly enjoying this show, especially as there's not much on barring True Detective and Masters of the Air that I watch. As for the low reviews, they can judge of course, the best critic is yourself, it doesn't float their boat, but please don't let that put you off. If you love British humour, the C Bomb dropping every episode and the so so violent scenes, I trust this will float your boat. A solid 8/10 from me or your money back.
