Like MI2 this one is also blown out of proportions with all sorts of gizmos and gadgets.The pace is good but the action is too unrealistic to believe.Agreed that Tom Cruise is the supercool hero of this film but after all he is also a human.Cant he never fail? The action scenes are breath-taking, though.If a similar kind of movie is tried out in Bollywood, critics would blast it with criticisms about it being very unrealistic.Just because it is a Hollywood film no one ever cares to give a second thought to whether it makes sense or not.Anyway, if you are trying to find sense then better not waste money..otherwise the film is enjoyable.
