If you’re looking for the Mission Impossible series to evolve or use the team it set up at the end of Ghost Protocol, then this feels more like a detour. One which toys with the idea of exploring the psychology of Ethan Hunt, the man who doesn’t know how to give up, and the anachronism that is the IMF, but really all it wants to do is celebrate that by strapping him to a plane. The movie that emerges is a lot fun, with silly, suspenseful missions, espionage fantasy, and enough humour to poke fun at itself. Rogue Nation was perhaps an opportunity to advance the series, but nothing much changes for Ethan. It’s a ride, an often exhilarating one, but ultimately like most rides it ends exactly where it began.
