I'm supposed to respect a private detective too dumb to wear a hat in the rain? It seems to think its mood is fascinating.I found it dull. Too much lingering over the unimportant.An utterly banal story idea, but faster paced it might have been OK.It was still a silly copy of a US tale, out of place.Making it ethnic did not help.

I feel for those who saw this in a theatre. I really do. We watched for ten minutes before returning to the start and turning on the translation. I admit I was surprised even then - the plot is rarely predictable or trite, and the pace varies with the prevailing emotions from scene to scene. The characters are relevant to current times and reasonably complex; even the gumshoe with the heart of gold (Riz Ahmed as Tommy Akhtar) has a few surprises for the viewer along the way. The language of cinema is present throughout, which is unfortunately unusual in modern films which have largely forgotten the roots of making movies. A dark but varied color palette and flashback sequences combine with the cinema verité feel of hand-held camera-work to convey a sense of time lost and passing. It's particularly effective in scenes with altercations, where the audience might see a fist or a movement of a body lurching. It's a much more effective method of showing physical violence than predictable mid shots. Repetition of short visual segments rearrange until the audience sees the events become linear and plot twists align. Corruption and loyalty are themes which move the plot through to the end.The principal characters' acting is convincing and without gimmicks. The cast is believable. Billie Piper is refreshingly mature, and the actress that plays her as a young woman was a good choice. Roshan Seth as Tommy's father is a natural charmer (unless confronted with reprehensible actions) and the supporting cast rounds out a picture of ethnic, religious and economic diversity which looks a lot like modern London.

Excellent gritty thriller! London multi-cultural mix with some superb acting and characterisations. I really liked Riz Ahmed in Four Lions & Rogue One. It was great to see him as lead and it is always nice to see Billie Piper :) Watch this, you won't regret it. XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX.

I really enjoyed this British take on the noir genre. It had a sensitive and moving performance by Riz Ahmed as a troubled PI. The plot, like all good noir, is satisfyingly layered. In addition to being an excellent whodunit, it addresses Islamophobia, the treatment of immigrants and the growing feeling that there are hidden agendas that affect our everyday lives. Not high budget or flashy but very well done. Highly recommended.
