Deciding Not To Accept It
Mission: Impossible—The Final Reckoning may well be the last of the "Mission: Impossible" movies, the series based on the espionage TV show that featured a crack-team of specialists engaged in "heist-movie" scenarios for the government.* The films had some of the tropes, the "fuse" logo, the late Lalo Schifrin's pulsating, propulsive theme, the clandestine mission briefing (that then self-destructed leaving no trace). But, in the movies it spawned, the "team aspect" always played second-fiddle to its star and champion, Tom Cruise, who increasingly dominated the films, while his character, Ethan Hunt, still remained a bit of a cypher as a character. Other than doing the hardest stuff, of course.
But this latest, maybe last, entry, given the evidence on display, indicates the series is past its self-destruct status. At nearly 3 hours in length, what could have been a lean and mean entry feels bloated with a first act crammed with flash-backs (ill-advised as they'd never connected story-lines before and even dropped connections with past movies at the drop of an un-negotiated contract) and a star who, at 62, is looking a little too doughy—in a Brad Pitt/Jerry O'Connell kind of way—to be romping around doing his own crazy stunts and skittering the world in his signature tin-soldier full-tilt run. 
All the worse, because this one really leans (and leans hard) in to Ethan Hunt being the end-all, be-all "only one" whose destiny it is to save the human race from Mutually Assured Destruction at the hands of an AI "anti-god" called The Entity...which featured in the last one and, it turns out, was the undefinable McGuffin dubbed the "Rabbit's Foot" from Mission: Impossible 3.** As The Church Lady would say "Isn't that convenient"***
"Oh, yeah, there are other people in the movie..."
And Ethan Hunt turns out to be as mythic a lynch-pin to world affairs as Luke Skywalker or Paul Atreides.
It appears original, but it's merely a re-gift, just put in a new wrapper.
They also serve—briefly—watching Tom do the hard stuff...
So, anyway, the mission should you decide to accept (and I didn't) is that after the events of Mission: Impossible—Dead Reckoning Part 1, Ethan Hunt was in possession of The Cruciform Key, which would allow him to somehow destroy The Entity which is embedded in the Interwebs and is slowly but surely filling it with misinformation, turning the World Wide Web into a cesspool that has man turning against himself (as if it needed any help!) with the eventual end of taking over the nuclear capabilities of all the world's powers. What it would do then is anybody's guess, but even a digital anti-god would know that anything actually using those weapons would create a nuclear pulse and wouldn't do it any good at all, disabling any electronics throughout the world. If it's aim is murder-suicide then you need some other term than "artificial intelligence". Artificial psychosis", maybe? The Entity sounds like it's related to Monty Python's "Black Knight" ("You're a loony!")
They also serve who sit in boardrooms and clutch pearls...
Anyway, getting the thing to destroy The Entity involves two impossible missions: get to the Russian submarine Sebastopol (scuttled in arctic waters in the last movie) to use his Cruciform Key to obtain the Entity's "Podkova module" (containg its source code); then, using a "Poison Pill" developed by IMF whiz Luther Stickell (Ving Rhames), get that module to the world's "Doomsday Vault" located in South Africa—a huge mainframe designed to withstand said nuclear pulse even in a planet-wide armageddon—and plug the "Pill" into the "Podkova" thus isolating the Entity and somehow managing to contain the thing.
But, there are complications—there always are—such as the sub Sebastopol starting to roll down a continental shelf when Hunt is inside it (evidently it doesn't have a conning tower or fins or sail planes or...ya know...rudders that might impede the progress), or Hunt having to discard his hi-tech diving suit to get out of a jam and swim...in just trunks...in arctic waters...with no oxygen...and no decompression gear (except on the surface), or—a major one—the bad guy Gabriel (Esai Morales) manages to steal said "Poison Pill" making his escape on a bi-plane (...a bi-plane!), thus forcing Ethan to hijack another one and do a godawful amount of gyrating on wings and struts to get on the bad-guy's plane to get said "Poison Pill."
Now, look...the plot-line is insanely complicated and stupid...way too much so...as well as being openly subject to criticism by what Hitchcock called "The Implausibles" (I can't wait to see the "Goofs" tab on its IMDB page). Such things as Hunt being able to take out two competent goons moments after biting down on a cyanide capsule, or being able to survive "the bends" or the crushing water pressure of a deep-dive while only in his swim-trunks, then being able to do all that dangerous wing-walking the very next day boggles everything that I have left of a mind. The onslaught of implausibles tend to overwhelm such trivial matters as grabbing the barrel of a recently-fired automatic weapon without scorching your hands in the process.
Still, I can appreciate the length and breadths—in IMAX, even!—to which the cast and crew have gone to present such shenanigans. The rolling submarine set that they present is a wonderful little concept design for all sorts of mayhem, and the whole bi-plane sequence is an amazing showcase for what can be done with remote cameras and a star with a death-wish (but one with a goofy absurdist sensibility). As an actor, Tom traditionally dials it to 11, it's in these insane stunts where these proclivities really pay off.
However, the movie is a logical and editorial mess, with sporadic flashbacks that don't quite connect dots or light emotional fuses. It does provide considerable down-time between action set-pieces to make an assault on a snack-bar or sabotage a theater restroom.
If that's your aim I will disavow any knowledge of your actions. Good luck.
*Poof!* hsssssss
Ethan cares, man. He really cares.
* I'm throwing a lot of stick here, but the TV series, as great as it could be, had elements rolled eyes. For instance: why did every potential, autocratic, generalissimo, and revolutionary look like Martin Landau?
** That was, what, 4 movies ago, the one with Phillip Seymour Hoffman, which, when you see him in the flashbacks, causes actual grief.
*** Yeah, okay, M:I fans, I know that the James Bond series just wrapped up an uncharacteristically continuity-obsessive five-film arc, where everything tied together to the point where Bond super-baddie Ernst Stavro Blofeld turned out to be the step-foster-brother (or something) of Bond—in a plot-twist borrowed from (of all things) the "Austin Powers" series. Connecting the dots has a way of diluting the power of a story. In the Craig years, Blofeld wasn't so much an international criminal as a red-headed step-child. Just like in the first Michael Keaton Batman, the criminal who became The Joker was the one to kill Bruce Wayne's parents, rather than just some rando gunman. It waters things down, sometimes to an unpotable degree.
