This is never supposed to be the case. Movie franchises are not supposed to improve with each sequel. We all expect them to get worse and worse to where you wonder why the filmmakers even bother making them anymore. But with the “Mission: Impossible” movie franchise, actor and producer Tom Cruise continues to work closely with gifted filmmakers to create motion pictures which defy expectations as he is intent on topping what came before. “Mission: Impossible – Fallout” is the sixth film in a series which began back in 1996, and it proves to be the most thrilling installment yet. I cannot wait to see it again, and I am determined to see it in a IMAX theater as this sequel demands to be seen on the biggest screen in town.

The plot of “Mission: Impossible – Fallout” is a bit convoluted, but I will give you the gist of it. The terrorist group from “Rogue Nation” known as The Syndicate has since reformed into The Apostles, and Ethan Hunt (Cruise) is tasked with intercepting the sale of three plutonium cores to them. But despite the presence of team members Luther Stickell (Ving Rhames) and Benjamin “Benji” Dunn (Simon Pegg), the mission is thwarted and the plutonium is stolen right out from under them. From there, they are determined to get the cores back, and their latest impossible mission has them meeting up with characters old and new to where alliances and methods are questioned endlessly. It all reminded me of what Mary Elizabeth Mastrantonio told Willem Dafoe in “White Sands:”

“You’re honest, even when you’re lying.”

Does everything we see here make perfect sense? No, but I really didn’t care. Even at 147 minutes, “Mission: Impossible – Fallout” never drags, and it is a movie I am happy to describe as exhaustively thrilling as it kept me on the edge of my seat throughout. Just when you think it’s over, we are pulled back into another astonishing action set piece which leaves us out of breath.

Let’s talk about the stunts, shall we? Among the first is the HALO (high altitude, low opening) jump which is a skydive from a seriously insane height. We all know how Cruise is a stickler for doing his own stunts, and while the average skydive is done from 7,000 to 9,000 feet, a HALO jump is often done from 15,000 feet and with the aid of oxygen. Taking this all into account makes this particular sequence all the more thrilling as it is done in what seems like an unbroken shot which would make even Alejandro Inarritu stare at the screen in awe.

There’s also a motorcycle chase through the streets of Paris, and I kept waiting for the characters to get seriously injured or killed as no one can navigate traffic like that in real life. And yes, it is indeed Cruise jumping from one building to another. Everything culminates in a thrilling helicopter chase which outdoes the ones I loved watching in “Blue Thunder,” and it is in this sequence where Cruise and company attempt to complete the most impossible mission of all as what they are tasked with doing has a higher probability of failure than success.

Cruise is now 56 years old, and he shows no signs of slowing down. While many be telling him to act his age, a term which has now lost all its meaning to me, he continues to defy the odds and show just how far he is willing to go to make an action movie which is anything but average. The scenes of him “grinning like an idiot every 15 minutes” are few and far between this time around as we instead see him playing mind games with actors who are playing characters not entirely trustworhty. And yes, there is the obligatory scene of him sprinting at warp speed, and I hope I am able to run like he does when I reach his age.

“Fallout” almost marks the return of writer and director Christopher McQuarrie, making him the first filmmaker to direct more than one “Mission: Impossible” movie. “Rogue Nation” was terrific entertainment, but he really outdoes himself this time out. His screenplay is full of endless plot twists and enigmatic characters to where I was quickly reminded of he was the same man who wrote the screenplay for “The Usual Suspects.” Seeing him balance various plot threads makes me admire him as a director even more as he brings everything together for a furious climax which is just staggering.

Simon Pegg has been great fun in the “Mission: Impossible” movies, but in “Fallout” we see his character of Benji Dunn evolve a bit. Granted, Benji has always served as the comic relief, but we see him become a better field agent to where, even when he whines about the things he doesn’t want to do, he can hold his own with Ethan to where he doesn’t have to perform a HALO jump to make this clear. Pegg has always been a great comedic talent, but he’s also a better actor than people give him credit for.

Ving Rhames continues to make Luther Stickell the uber cool IMF agent, and Luther has evolved to where he is not as concerned about his expensive taste in clothes anymore. Rebecca Ferguson, who all but stole “Rogue Nation” as Ilsa Faust, once again makes her character wonderfully enigmatic to where I was desperate to get at the secrets inside Ilsa’s brain. Alec Baldwin has more fun this time around as Alan Hunley, Sean Harris makes “Rogue Nation” baddie Solomon Lake even more sadistic than ever before, and Michelle Monaghan once again provides this franchise with a warm human presence as Ethan’s ex-wife, Julia.

We also get introduced to some new characters including Erica Sloane, the new CIA director played by Angela Bassett. Although we don’t get to see much of Bassett here, she reminds us of how badass she remains after all these years. It has been 25 years since she broke through as Tina Turner in “What’s Love Got to Do with It,” and she hasn’t let us down since.

Acclaimed stage actress Vanessa Kirby makes her American film debut as White Widow, a black-market arms dealer. Kirby makes this character such an alluring presence as she keeps her cool even as her life is constantly being threatened and as she dangles a plutonium core right in front of Ethan’s eyes, knowing full well just how much he wants it.

And, of course, we have Henry Cavill who gets to take some time off from his day job playing Superman to portray CIA assassin August Walker. Cavill is a bit stiff in some early scenes to where he threatens to get upstaged by his mustache, the same one he was unable to shave off for “Justice League” reshoots. For a time, I kept waiting for him to say, “It’s just you, me, and my mustache” as such a big deal was made about it having to be digitally removed. But as “Fallout” goes on, Cavill makes August into an especially dangerous character who is never to be trifled with. And while he may not be playing the Man of Steel here, he throws punches which had me thinking his arms were made of steel.

Seriously, “Mission: Impossible – Fallout” is the best movie yet in this franchise, and it may very well be the best action movie of summer 2018. Just when I thought nothing could top the sight of Cruise climbing the Burj Khalifa tower in “Ghost Protocol,” we are given some of the most amazing stunts, and they are coupled with characters busy playing mental chess games with one another as what the eyes reveal can be even more threatening than a bullet to the head. “Fallout” is a thrilling spectacle, and it makes me wonder if Cruise and company can possibly top what they have accomplished here.

Cruise had a tough time in 2017 as “The Mummy” reboot proved to be a critical and commercial bomb, and the biographical crime film “American Made” underperformed at the box office. It’s a good thing he still has “Mission: Impossible” to fall back on as he always pushes himself to outdo what he did previously as an actor and producer. Just when I thought his career would self-destruct in 5 seconds, he manages to come back with a vengeance.
