Filled with action, intrigue, suspence, and just a little romance, M:I:3 is a perfect way to kick off the summer, or finish off the day. Watching it, you forget that you don't like Tom Cruise, and find yourself worried for the safety of Ethen Hunt, and the completion of his mission.
I have not seen the first two M:I movies, but each is its own story, so you don't need to.
Actually, this is the best movie I've seen in theaters in a year!
