In Adam Wingard's Onslaught, when a rogue squad of genetically engineered super soldiers break loose in the desert, a badass Army sniper must unleash hell to protect her young daughter.

The movie stars Adria Arjona, Dan Stevens, Eric Wareheim, Reginald VelJohnson, Michael Biehn, Alex Pereira, Drew Starkey, and Rebecca Hall. The project also marks Wingard's long-awaited return to original genre fare after several years spent in the MonsterVerse with Godzilla vs. Kong and Godzilla x Kong: The New Empire.

As we first reported on FearHQ.com, the review embargo for Onslaught lifted today, and that means we have an all-important Rotten Tomatoes score. 20 verdicts have been counted as we write this, but that's enough to earn it a "Fresh" 80% on the Tomatometer.

The Guest remains Wingard's best-reviewed movie with a "Certified Fresh" 92%. His lowest-rated feature is 2011's little-known Autoerotic with 30%.

"Adam Wingard throws a collection of action and B-movie genre influences into a blender," writes IGN, "pushes that concoction across the table, and encourages you to chug."

Slashfilm notes, "What we wind up with is a synth-draped, unabashedly violent, grindhouse-y grab bag of Carpenter-esque elements that makes this feel like the single greatest John Carpenter movie that John Carpenter never made."

"The film pushes The Guest’s exploitation-movie excesses farther, and appropriately so, suggesting Assault on Precinct 13 by way of The Prowler," adds Slant Magazine. However, Next Best Picture cautions, "Onslaught" succeeds in most of what it tries to tackle, even if, at the end of the day, its core is a bit too familiar for a film trying to break the mold."

The Film Verdict was even less impressed, concluding, "Wingard and Barrett are clearly going for gut-bucket grindhouse here, but even by those particular standards, Onslaught arrives as a particularly loathsome bucket of guts." Over to The Hollywood Reporter, and the trade declares, "Adria Arjona shines in Adam Wingard’s intriguingly colorful, ultimately underwhelming action thriller."

io9 was similarly disappointed. "A film filled with beautiful visuals, solid action, incredible actors, and fun ideas, almost none of which come together in a satisfying way," the site bemoans, only for Den of Geek to counter, "Sometimes you just want to see mom grab the sniper rifle, say everything is going to be alright, and then expel the boogeyman in a blaze of glory."

How will Onslaught fare at the box office this weekend? This type of movie rarely attracts a large audience, so we're not expecting it to pose much of a problem for Spider-Man: Brand New Day, which will likely remain at #1 for the sixth weekend in a row. 

Onslaught arrives in theaters this weekend. Will you be checking it out on the big screen?

I'm over the usage of chainsaws in horror movies. It's like studios and directors are so desperate to steal outdo Leatherface every opportunity they get. I feel like chainsaws in horror are such a cop out when it comes to quick messy scenes.

Interesting , I feel this is the first time I saw a movie get mixed reactions but the reviews themselves were more positive then not atleast so far.

Anyway , the movie has looked fun so I’m excited to check it out though not sure if it will be in theaters honestly…

Also , this and By Any Means definitely won’t do much if anything to put a dent in BND’s B.O so Spidey will likely be no 1 this week (and next week)!!.

This movie will be better than Doomsday.
Shit, everything is much better than Doomsday except for BND, that movie is a hot pile of shit.

@Nolanite - I’m with you as a fan of Nolan. I liked and defended Gunn’s Superman and even Supergirl. I’m annoyed currently at what they’ve done to Hal and Stewart but even with that I’m still rooting for DC.

But dude you are CRAZAY in denial about Marvel’s current station. Punisher one shot was great. Daredevil was close enough to good lol. Spider-man was exceptional. And the next two Avengers movies are directed by the Russos who made 4 really good to even great Marvel movies.

Don’t be so wrong 😂

@Nolanite - also fairly confident that Onslaught will be a snore fest for the record!

@Lucasberg -

Thank you for your appreciation of the DC Brand. I loved Supergirl and Superman and also Lanterns. I kinda hate the thing with Hal but John Stewart is GREEN LANTERN. He's most known to the public as the Green Lantern.

Remember, if Kyle Chandler is up for it, they can always go back in time for any other projects. They already have the actors, so it could be a possibility.

Hang on buddy because the ride just started!

@Nolanite - I really really like Chandler as Hal! He’s freaking awesome. The dude playing Stewart as well is perfect. It’s just that writing man.

Anyhow, Supergirl was unjustly destroyed by edgelords. It wasn’t the best superhero movie ever but way the frick better than what was portrayed by the myriad critics

Hey @JoshWilding I am not sure if you've been keeping up with the ratings and reception/WoM effect this movie's had since this article was posted. Because things drastically changed over the course of the week.

Even though I wasn't that interested in this film I thought it should do fine since it's an A21 production and more after we got the initial RT score of 88%, but never thought that in just a couple of days it would drop so much to match Supergirl's. Ouch.

Not a good hype-esque look for Arjona as she's still rumored to be actually playing Wonder Woman in the DCU, certainly.
