In a series that hit its peak in the previous installment, Christopher McQuarrie’s Mission: Impossible – Rogue Nation (B-) is nonetheless a perfectly competent thriller with a durable action star. There’s one really great heist sequence involving having to swim to unlock a computer code, but it’s mainly mission improbable with car chases and thwarted torture and opera assassination attempts. Tom Cruise and ensemble may be able to crack a code but rarely crack a joke in this straightforward and overlong spy thriller.
