It's an acceptable action film, filled with exaggerated sequences, but it doesn’t quite capture what makes a Mission Impossible movie. The initial portion is fairly good, showing some intelligence and hinting at the familiar Mission Impossible style; there were even moments when it felt a little slow. However, the latter half descends into a standard John Woo-style action spectacle, abandoning any sense of cleverness or connection to the established series. John Woo doesn't seem like the right choice for directing a Mission Impossible film. Like the first installment, if this hadn’t been branded as Mission Impossible, I likely would have rated it better because it is a perfectly adequate, albeit largely empty-headed, Hollywood action movie. But my expectations are higher when something carries the Mission Impossible name. Tom Cruise performs adequately in the role of Ethan Hunt. Dougray Scott is passable as the antagonist; occasionally he embodies the menacing and formidable villain persona, but at other times he just seems ridiculous and as excessive as the action itself. He’s presented as a mastermind, yet often appears more like a brutish drug lord in numerous scenes. The action sequences are characteristic of John Woo's work: rapid-paced, packed with stunts, and featuring plenty of explosions. Predictably, they are quite overblown and unrealistic, delivering an enjoyable visual experience, but again, not what I’d anticipate from a Mission Impossible film. The romantic subplot between Hunt and Nyah is the usual Hollywood formula—inserting a female character to create superficial attraction that rapidly evolves into “I love you” after only a few hours of interaction. It's uninspired. It gives me the sense that those involved in creating these films haven’t really viewed even one complete season of Mission Impossible.
