There's great fun to be had in seeing Michael Douglas and Kiefer Sutherland chew up the scenery (as well as their fellow actors) as Secret Service agents struggling to unravel a plot to assassinate the president. Too bad The Sentinel doesn't offer much more.
Instead, the movie - based on a novel by Gerald Petievich - offers a setup that inexplicably goes away about halfway through, characters who seem to have missed much of their Secret Service basic training, atmosphere that doesn't really have to do with anything and way too many guys with machine guns within easy reach of the president of the United States.
