'Annihilation' might end up being the year's best science fiction mind trip, while 'Game Night' delivers one laugh after the next.

One of two problems sink your average science fiction film.

The big reveal is a big ol’ bust, or genre formula kicks in and won’t let go. Neither happens with the mesmerizing “Annihilation.”

Writer/director Alex Garland (“Ex Machina”) transcends our expectations like someone who’s seen every science fiction film ever made and demanded something different. Fresh. Invigorating. New.

That’s what we get – two stunning hours that leave us both satisfied and hungry for more.

Natalie Portman stars as Lena, a biologist mourning the disappearance of her military beau (Oscar Isaac). His sudden reappearance delights her, but the joy is short-lived. He begins coughing up blood and ends up in an ambulance.

A stark series of events reveals what happened to him. He entered a mysterious zone, dubbed the Shimmer, which took over a parcel of land. And the Shimmer is growing. No one who enters comes back. Lena wants to follow in her boyfriend’s tracks all the same, in part so she can figure out what happened to him.

She’s joined by four female recruits, each with different skill sets and reasons for attempting what likely will be a suicide mission.

FAST FACT: Alex Garland based “Annihilation” on a 2014 novel by Jeff VanderMeer. The story is part of series dubbed the Southern Reach trilogy.

What happens next is a series of jolts, reveals and action that come at us in wholly unexpected ways. The Shimmer distorts more than time and memory, a lesson the women learn as they head toward what they think is the field’s center.

Garland develops a naturalist tone that embraces science while gently tugging at its boundaries. The special effects are subtle at first, landscape tweaks that could be nothing … or everything. Clues begin to pile up, and the brainiest of the bunch (Tessa Thompson) theorizes what the source behind the Shimmer’s impact.

“Annihilation” delivers some first-rate chills but is in no hurry to let them loose. The screenplay touches on the human condition, our fallible nature and the motivations that influence our lives.

Sound heavy handed? It might be in less capable hands. Here, the discussions flow from the situations the women find themselves in.

“Annihilation” doesn’t deliver characters with the weight of, say, “Alien.” It’s still a pleasure to watch the women process this strange new realm.

If there’s a weak link here it’s Portman. She’s clung to the vocal affect that brought the title character to life with 2016’s “Jackie.” It’s a modest complaint. She’s steely eyed when the situation demands it and a fine audience conduit. Her cast mates (Thompson, Gina Rodriguez, Jennifer Jason Leigh and Tuva Novotny) offer compelling shades that contract with Portman’s numb approach.

Garland’s “Ex Machina” proved a minor revelation. His latest reveals an auteur who not only adores science fiction but is capable of bringing out its very best on screen.

HiT or Miss: “Annihilation” offers more proof we’re in a golden age of science fiction.

“GAME NIGHT”

Will we ever get tired of Jason Bateman playing Jason Bateman?

The “Hogan Family” alum set his bemused persona in stone during his “Arrested Development” days. He’s been riffing on it ever since, finding new wrinkles with every project. You can even see it peeking out from the doom and gloom that is Netflix’s outstanding “Ozark.”

“Game Night” puts the Jason Bateman template to fine use. Bateman plays a happily married man who lives for Pictionary smackdowns. He’s in his comedic element, again, and he’s confident enough to let his co-stars steal every other scene.

One does it by simply stroking a small pet, Blofeld style.

Bateman and Rachel McAdams play Max and Annie, a childless couple who build their social calendars around their game night festivities. Max’s brother Brooks pays them a visit, vowing the greatest game night of them all.

That’s what Brooks does, roll into town with the promise of unchecked wealth and gaiety. And Max hates him for it. You can’t blame him.

Brooks’ latest trick backfires in a big way. What begins as a murder mystery game gets real fast. Brooks is hauled off by a pair of thugs, leaving Max, Annie and their friends thinking it’s all an elaborate act.

Try again.

Jason Bateman, Kyle Chandler and Lamorne Morris star in the new dark comedy ‘Game Night.’

Can the couples rally their resources to rescue Brooks? Will Max and Annie come to grips with their ambivalence about starting a family? Just who is the celebrity Michelle (Kylie Bunbury) bedded while on a break from her beau (Lamorne Morris)? And can the friends save the day while dodging the annoying neighbor from hell?

“Game Night” starts strong, delivering one solid laugh line after the next. Some howls come with just a frozen glance. Yes, that’s Jesse Plemons of “Fargo”/”Black Mirror”/”Hostiles”/”The Post” fame, owning every second of his modest screen time.

He’s the creepy neighbor who can’t let go of his ex’s memory, or the fuzzy white dog that’s his constant companion. Plemons’ blank look is funnier by itself than last year’s sorry comedy lineup. Yes, we’re looking at you, “Fist Fight,” “Baywatch” and “Rough Night.”

Sure, “Game Night” is a smart, sophisticated riff on relationships. You still keep waiting for the inevitable. The jokes will dry up. The story line will get so convoluted you’ll mentally check out. The characters will change course dramatically, leaving us without a connection.

No, no and no.

It doesn’t take a movie connoisseur to predict the third act will offer a twist demanding serious belief suspension. That’s how modern movies work. They rarely trust audiences will accept a straight, streamlined narrative.

FAST FACT: Jason Bateman’s first acting gig came at 12 with the long-running series “Little House on the Prairie.”

What’s left is still engaging, even intoxicating at times. McAdams is a hoot, alternately a worrying wife and a neophyte sleuth. Billy Magnussen injects a freshness into the guy who dates vapid model types that you won’t see coming.

Even the running gags boast a high batting average. One starts in a clumsy fashion but rallies strong in the delirious final moments. We won’t spoil it here, of course. It doesn’t matter if we did. “Game Night” has a dozen more waiting in the wings, one funnier than the next.

HiT or Miss: “Game Night” ends with a predictably wacky third act, but the movie’s sly humor and palpable heart never stops beating.
