Philip Seymour Hoffman portrays "Andy," who finds himself needing money to avoid an IRS audit, while Ethan Hawke’s character, “Hank,” is dealing with financial issues related to his divorce and childcare arrangements. To resolve both situations, the brothers devise a scheme to rob their parents' jewelry store, intending to affect only the insurance company. However, a change in staff alters those plans; it turns out their mother isn’t as easy to deal with as they thought, and the robbery quickly spirals into disaster, resulting in the deaths of their mother and one of the robbers. "Hank" is experiencing emotional distress, "Andy" still has his own financial troubles, and now their father (Albert Finney) is set on finding out who was responsible for the attack. Complicating matters further, “Hank” is also involved in an affair that’s uncomfortably close to home for his brother, creating a palpable build-up of tension that will inevitably lead to a violent breaking point. Although Finney's appearances are limited, he manages to be memorable as the dynamic between Hoffman and Hawke intensifies toward a strong and impactful resolution which effectively demonstrates that families aren’t always harmonious. It is a well-constructed narrative with good casting and writing; Sidney Lumet largely stepped back, allowing his talent to carry the film forward without excessive dialogue or directorial flourishes. I appreciated the ending as well.
