It's more like
The "Fine"-al Reckoning, am I right?

It's more of the complete nonsense plotting of
Dead Reckoning, but with a dour tone that's closer to
Fallout. I don't care about Luther dying when he's had zero character development for the past five or six flicks, and now that Gabriel has gone rogue, The Entity's vague and undefined mission to exterminate humanity just plays like a tired retread of Skynet and Ultron, with none of the quick-thinking mystique it had in Part One.
Sure, the two major stunt/action sequences are fun enough, but they're both variations on what we've seen before, and there's no heists whatsoever this time. Hayley Atwell of course remains charming, but her and Ethan's vague
siblings-in-arms,-or-maybe-someday-lovers? chemistry also mostly just replays his quasi-relationship with Ilsa. Meanwhile, the movie's whole "Ethan Hunt/Tom Cruise is
literally Jesus" shtick was tiresome throughout, and, given the story's sci-fi angle, it's impossible (har, har) not to be reminded of Cruise's, uh,
personal life. All told, apart from an homage to
Fail Safe, (the US president having to proactively nuke a US city as a conciliatory, escalation-suppressing measure), there were really only two new elements here: the unexpected and genuinely sweet story about the bit player from the first flick, and
at least 10 seconds of screen time that seems to be arguing the world's best medicine is a few hours' exposure to Atwell's bosoms, which, sure, can't argue with
that.
In conclusion, the movie left me satisfied on the action front, but wanting to rewatch either
2 or
Ghost Protocol to experience a proper popcorn spy story.
III,
Fallout,
Dead Reckoning, and
The Final Reckoning all have standout action sequences, but I don't think I'd ever rewatch them start to finish on my own, and I might even include
Rogue Nation on that list. (I haven't seen the original recently enough to fully rate it, but I didn't much like it the first and only time around.) That may sound a bit harsher than I intend, as I don't outright
dislike any of those movies; they're just not particularly satisfying stories.
Dead Reckoning Part One:
B+
The Final Reckoning:
