Towards the end, when Koslow is on the cell phone with his daughter and gets disconnected, an old style dial tone is heard. Such a simple obvious mistake. See more »

User Reviews

Great acting, tight script, gritty
30 August 2019 | by tobycrossSee all my reviews

What a nice change to get away from the 'typical' Holywood action flick and to get into a grittier, morally ambiguous, uncompromising drama. Rosamund Pike continues to prove what a great actor she is with a performance that echoes her character in Beirut. Joel Kinnaman gives a performance that is just as conflicted and compelling as Altered Carbon. Altogether a great cast that manages to build realistic characters. My only criticism of the script is the overly detailed explanation of fentanyl that Pike gives to her team on FBI agents - it's the only point where you feel the film patronises the audience. Other than that, a thoroughly enjoyable movie.
