I remember MI3 came out after a long break and was very sub-par. Thought that would be it for the franchise. Then 5 years later Ghost Protocol comes out and is simply amazing, followed by Rogue Nation that was also excellent.

So yeah, pretty excited for number 6. As others have said, TC is also seriously impressive after all these years, especially doing most of his own stunt work.

Edit: Worth noting it has the highest reviews of all MI films, both with reviewers and audiences.

He's great in Eyes Wide Shut and Tropic Thunder as well.

I liked it. It's Mission Impossible, so it is totally ridiculous, as expected.

Now THIS is how to do a modern action film.

Saw it last night. Overall, as far as the action elements go, this is as good as it's ever been; I can't think of a better high-level action film. Very visceral, intense... And this is why the spy-action genre will always be better than superhero and Star Wars films; the spy action films (especially since the Bournes) look more realistic and far more intense, not a bunch of unnatural cartoony CG-balloons that even motion capture hasn't seemed to save (Well, a few exceptions, notably Logan had some good action bits, and even Deadpool did some good stuff despite being purposely cartoony).

The major goof I noticed was the huge club and the almost empty washroom =D
Unless it wasn't alcohol they were doing.

MI3 is still the best one overall, there still has not been a film in the genre that has gone that dark or intense. I want to say MI1 is the best from an artistic standpoint, but they all are quite good - MI1 did a lot of homages to Alfred Hitchcock in its shots; I appreciate that. Purely from within the action film genre, the sequences of MI6 make it a contender as the best action film currently in existence. The 3D effects during the chopper stuff at the end were really well done.
