30 years, eight films, heaps of death-defying stunts - the Mission Impossible films are undeniable. Not everyone is convinced this will in fact be the last mission before Tom Cruise passes the MI mantle to another star (Glen Powell?) or ropes in another director (Iñárritu?), but The Final Reckoning is nevertheless a flashback-filled, legacy-cementing ode to one of the most profitable, star-making, one-of-a-kind action franchises of the 21st century, and a bittersweet farewell to the creative marriage between Cruise and writer-director Christopher McQuarrie.
