In fact, with each episode it gets better and better. Low-key but smart. The dialogues are crisp. The pace is breathtaking without being overwhelming. Stereotypes are skilfully avoided. And nothing is ever what you expect it to be; the characters never do what you expect them to do. Honestly, this is the best of the best in my opinion. Enjoy!”A user review posted to IMDB reads: “Intelligent thought provoking drama. Terrific performances. Carrie Mulligan as DI Kip Glaspie brings something new to the genre of crime fiction, compassion and intellect. An outstanding and intelligent drama all round. Outstanding script, direction and cast.”While one fan of the series says: “The British are so good at this. Decent script, very good acting, excellent direction and cinematography. Well worth binging on. Solid offering. Recommended.”Another glowing IMDB review says: “It was extremely well done in every aspect, and though a slightly slower paced than many of my favourite shows and films, the production is superb and kept me spellbound."What most have ignored here is the incredible cinematography and editing work that went into this, and I feel it's some of the best I've seen in some time. I really hope to see more of this series.”While one viewer lauded the exceptional cast: “Exceptional cast of women involved in this mini-series. Nathaniel Martello-White also does excellent work.”Article continues belowCollateral is available to stream on Netflix.
