While it’s hard to call this Guy Ritchie's finest film, and Henry Cavill seems as stiff as his facial structure—but there are things about it worth appreciating. The movie doesn't seem concerned with being taken seriously; you get plenty of gadgets, fashionable outfits, and even a hint of music reminiscent of Morricone’s work. Taking place during an era defined by cold war suspicion, Illya Kuryakin (played by Armie Hammer with a deliberately exaggerated accent) teams up with Cavill's character, Napoleon Solo, to stop a shadowy group similar to Spectre from spreading nuclear weapons. Alicia Vikander and Elizabeth Debicki add some visual appeal—and contribute significantly to the little bit of threat this rather underwhelming movie creates. I’m not certain if it was meant to be (or isn’t) something like "Bond" combined with "The Saint"—but it's clearly a parody; there are several amusing moments, and Hugh Grant manages to make an impact in his limited screen time as the mysterious Waverly. It surpasses the original television show, certainly, but perhaps that’s also its flaw—it feels overly polished and refined when what it needed was something more basic.
