I remember talking to someone about Die Hard 4 and they were critical of the movie because of the astonishingly unrealistic feats that John McClane lives through and I'd say they'd have the same opinion here as it's taken to another level with Ethan Hunt. I preferred the slightly more realistic tone of MI:3 to this. While it grew on me in the second half, I wasn't feeling the first half of the movie much. I think part of that feeling was that I dislike Simon Pegg's character a lot, particularly when he's not just an IT whiz. Why do writers of movies like this think you need comedic elements, or attempts at them? There is no way someone like Benji would be an agent in the field alongside someone like Ethan. It removes any believability the film and series develops. Finally, I am glad there was a twist with Ethan's wife, or otherwise it basically made MI:3 meaningless.
