Every so often, Hollywood coughs up a family-friendly horror-adventure that reminds us of the golden age of “kids on bikes doing highly unsafe things while adults behave incompetently.” Monster Summer is that cough — a warm, nostalgic phlegm-ball of summer vibes, creature chaos, and Mel Gibson wandering around like he just escaped from a neighboring set where he was filming a gritty noir.
And somehow? It works.
Not all of it. This movie occasionally stumbles like a dad at a barbecue trying to relive his glory days on a slip ’n slide. But Monster Summer has enough charm, heart, and monster mayhem to win you over, even as you mutter, “Should children really be handling this much explosive equipment?”
Plot: Kids, Monsters, and One Extremely Overqualified Retired Detective
The story follows Noah Reed (Mason Thames), who spends his summer on a picturesque island where the biggest usual threat is sunburn or fishermen arguing about who stole whose bait bucket. But that changes when a mysterious force starts interrupting everyone’s big summer fun — ruining fishing trips, interrupting baseball games, and probably lowering property values faster than you can say “cryptid infestation.”
Naturally, Noah teams up with his nerdy, excitable friend Eugene, his brave buddy Sammy, and Ben, the kid whose personality is “likes food.” Together, they investigate the strange occurrences in the traditional way children always do in movies:
-
wandering into restricted areas
-
ignoring every adult warning
-
finding clues the police miss because the police are too busy doing paperwork or grilling sausages
And then there’s Gene Carruthers, played by Mel Gibson with the energy of a man who just woke up from a nap in a recliner holding a remote and decided to solve a mystery. Gene is a retired detective who reluctantly helps the kids — mostly because they annoy him into it.
Honestly, the real mystery isn’t the monster. It’s how these children convinced a grumpy adult man to follow them into danger. I haven’t seen this level of persistence since a Girl Scout almost forced me to buy a whole crate of Thin Mints.
The Monster: Less “Terrifying” and More “I’d Like to Pet It but Also Run”
Let’s talk about the creature. Without spoilers, the monster isn’t exactly nightmare fuel. It’s got more “sassy cryptid energy” than “I’m here to eviscerate you.” The CGI wobbles occasionally, but that’s part of the charm. It’s 2024 — if a creature feature looks just slightly better than a 90s PC game, I’m satisfied.
The film wisely avoids overexposing the creature too early, teasing it with shadows, splashes, and ominous forest movement — the cinematic equivalent of a monster flirting.
Is it scary? Not really.
Is it fun? Absolutely.
Would I adopt it? Probably, with a fenced yard.
The Kids: The Real Monsters… of Enthusiasm
Movies with child protagonists are a gamble. For every Stranger Things ensemble, there are five groups of kids who couldn’t act their way out of a wet paper bag — even one that’s already torn.
But Monster Summer has a shockingly lovable main trio.
-
Mason Thames as Noah: Our earnest hero. He’s brave, emotional, and manages to look genuinely terrified and inspired at all the right moments, which is more than some adult actors manage.
-
Julian Lerner as Eugene: This kid feels genetically engineered in a lab to play “quirky tech friend.” He delivers exposition like he’s auditioning for Bill Nye: The Anxiety Years.
-
Abby James Witherspoon as Sammy: The voice of reason… whenever she remembers to be. Sammy feels like the person who would survive the longest in a real horror scenario.
And Ben, the fourth friend? He brings snacks, falls down at least once, and nearly gets eaten. Every friend group has one, and if yours doesn’t… congratulations, it’s you.
Mel Gibson: Grumpy Dad Energy but with a Gun
Look, say what you will about Mel Gibson — the man knows how to play a cranky retiree who reluctantly helps children. He delivers lines like a man who wants nothing more than to go home, crack open a beer, and yell at his television because someone replaced his cable package.
And it works.
His character’s dynamic with the kids is peak “I did NOT sign up for this, but I guess I’m babysitting a monster now.”
He also has a handful of one-liners that remind the audience:
“Ah, yes. This is the man who starred in Lethal Weapon.”
Lorraine Bracco: The School Administrator Who Has Seen Too Much
Bracco plays Miss Halverson, a woman so overworked and underpaid that she could probably stare down the monster without blinking. She gives the performance of someone resigned to the idea that the island is falling apart and the children are once again behaving like gremlins hopped up on Capri Sun.
She delivers her lines with a tone that screams, “I should have retired in 2003.”
Iconic.
Is the Movie Good? Shockingly, Yes.
But don’t get too excited — not everything works.
The pacing sometimes drifts like a lazy river ride. The emotional beats occasionally land with the grace of a pelican crashing into a pier. And a subplot involving adults arguing about how to handle the monster feels like it escaped from a much more boring film.
The script is basically a Frankenstein patchwork of:
-
classic Spielbergian kid adventure
-
mild Scooby-Doo chaos
-
light horror
-
and exactly one scene where a child should have died but didn’t
But the film never pretends it’s reinventing anything. It’s here to entertain:
-
bright colors
-
summer fun
-
mild danger
-
funny banter
-
a monster who looks like it has seasonal allergies
It’s comfort food cinema — the kind of movie you watch with popcorn, not thoughtfulness.
The Final Act: Explosions, Emotions, and Questionable Child Safety Protocols
The finale is delightfully unhinged. The kids improvise a monster trap that would absolutely get them sued in real life. Gene shows up with the energy of a man who is two days away from retirement (again). The stakes rise. The monster roars. Someone definitely violates several environmental protection laws.
And in the middle of it all… friendship prevails.
Is it cheesy? Absolutely.
Did I smile anyway? Like a fool.
Final Verdict
⭐️⭐️⭐️⭐️☆ 4/5
(One star is purely for the monster’s confused little face.)
Monster Summer is not prestige cinema. It’s not arthouse. It’s not reinventing the horror wheel. But it is a wildly fun, surprisingly heartfelt creature adventure with kids, chaos, and Mel Gibson yelling at a lake.
If you want something spooky, silly, and nostalgic — a film that feels like summer vacation and unfinished homework — this one’s for you.
Even the monster would agree. Probably. If it understood English.
