First off, it's funny that plenty of my friends are on a Mission Impossible kick as of late, but watching these movies has proven that the entertainment value of these films progresses with each sequel, giving any viewer seemingly endless amusement.
As someone who saw M:I: Fallout first, then went back to M:I:1, then watched M:I:2, I can see M:I:III's luster as well as its rust. As effects and stunts improve, it's easy to see that action films do not often age well. That's not to say that the action in M:I:III is lame. Far from it. Still, it does not contain the level of action and suspense M:I:Fallout does, mostly leaving it with a typical "Spies stop villain from getting McGuffin" storyline. Still, the action scenes and stunts are phenomenal, Hunt's wife's involvement in the storyline adds suspense, and some great performances make this film above average for an action film.
