Stallone portrays an aging hitman caught up in a chase with a younger assassin seeking to claim the top spot. He joins forces with a computer expert as he confronts both his pursuer and a past trauma. Antonio Banderas and Julianne Moore provide supporting performances, while Richard Donner directs and the Wachowski brothers wrote the screenplay; Assassins seemed destined to be a high-quality action film. Unfortunately, that potential remains unfulfilled. There are indications the filmmakers intended something more profound and thoughtful, but what emerges is an excessively intricate—and lengthy—movie. While it features impressive action sequences, notably a wild taxi chase reminiscent of John Woo’s style, the movie falters in its central portion, becoming unnecessarily slow-paced. By that point, Banderas' character feels less like a menacing figure and more like a frenetic child; Donner seems to struggle with this aspect, though he does elicit an intriguing performance from Stallone. Moore delivers a strong portrayal and is given some worthwhile lines to deliver—a relative rarity, as much of the dialogue is mumbled or delivered in such a tense or gloomy tone that it’s difficult to understand clearly. It's not terrible, and functions adequately as a way to pass time, but numerous flaws and questionable choices in production keep it from rising above mediocrity. 5/10
