"Mission: Impossible — Dead Reckoning Part One" surely has the longest, most grammatically complex title of the year. But underneath the colons and em-dashes is the seventh Mission: Impossible film, and it's excellent. Every movie stars Tom Cruise as Ethan Hunt, and sometimes the movies have felt a little too heavy when they try to give Ethan too much depth (Ethan doesn't wear sadness well). But "Dead Reckoning Part One" figures out how to give Ethan deep emotional connections without weighing him down. "Mission: Impossible 7" is, in a weird way, about found family, about fighting back despite the odds, about what we owe each other in an ever-changing world. And yes, the stunts are excellent.
