I fully expected director, David Fincher's new film to be a stone cold Day of The Jackal look into the mind of an assassin. It isn't, its a far more rote and overdone revenge story, yet at the same time, the level of class every single aspect of its making possesses, the awards worthy performance of a long absent Michael Fassbender and the fact it leans fully into black comedy, makes it feel new and incredibly watchable.
