Joe Ballarini wrote a book about a secret society of babysitters. Then Netflix turned it into a movie. Honestly, when A Babysitter's Guide to Monster Hunting dropped in 2020, people kinda shoved it into the "just for kids" pile. Big mistake. It’s actually a pretty dense piece of world-building that taps into that specific 80s Amblin energy we all pretend we're too cool for now.
You've got Tamara Smart playing Kelly Ferguson. She’s a math genius—which is a refreshing trope—who ends up babysitting on Halloween. Then, the Boogeyman shows up. Not just any Boogeyman, but Tom Felton chewing the scenery as the Grand Guignol.
It’s weird. It’s colorful. It’s surprisingly tactical.
The Lore Behind A Babysitter's Guide to Monster Hunting
Most people don't realize this started as a book trilogy. Ballarini didn't just wake up and decide to write a screenplay; he built a whole mythos. The Order of the Babysitters isn't just a bunch of teenagers with flashlights. They have a manual. They have international branches. They have specialized tools.
The movie focuses on the "Toadies." These are the lumpy, mischievous little minions that the Grand Guignol sends out to do his dirty work. They aren't just CGI blobs; they represent the specific fears of the children they kidnap. That’s the core hook. The monsters in this universe feed on nightmares. If a kid dreams it, the Grand Guignol can make it a reality.
Basically, the "Guide" is a textbook on how to handle supernatural entities using household items modified with a bit of "monster science."

Why the Math Angle Actually Works
Kelly Ferguson isn't a warrior. She’s a nerd. In the film, her ability to calculate trajectories and patterns is what actually saves the day. It’s a nice pivot from the "chosen one" narrative where the hero is just naturally good at punching things.
Rachel Talalay directed this. If that name sounds familiar, it should. She’s a veteran. She directed Freddy's Dead: The Final Nightmare and worked extensively on Doctor Who. You can see that influence in the production design. The monsters have a physical weight to them. Even though it's a PG movie, there’s an edge to the visuals that feels a bit more "90s dark fantasy" than "modern streaming filler."
The Grand Guignol and Tom Felton’s Transformation
Let’s talk about Tom Felton. We all know him as Draco Malfoy. In A Babysitter's Guide to Monster Hunting, he is almost unrecognizable. He’s lanky, greasy, and looks like he hasn't slept since the Victorian era.
He plays the Grand Guignol.
In the lore, he’s one of the seven Monster Kings. This is where the movie sets up a sequel that we are still waiting for. The film implies a much larger world where different Kings rule different types of fears. Felton plays it with a rockstar-gone-wrong vibe. He’s theatrical. He’s campy. But he’s also genuinely unsettling for a younger audience.

He wants to use the brain of a gifted child named Jacob to manifest an army of nightmares. It’s a classic high-stakes plot, but the execution feels fresh because the "superheroes" are just girls with heavy backpacks and specialized knowledge.
The Support Cast and the International Order
Oona Laurence plays Liz Lerue. She’s the veteran babysitter who introduces Kelly to the Order. Her character is the "cool older sister" archetype, but with a lot of trauma under the surface. Her brother was taken by the Grand Guignol years ago. This adds a layer of emotional stakes that prevents the movie from being purely slapstick.
The Order operates out of a secret base. It’s very Men in Black but for toddlers. They use "Monster Toots" (yes, that’s the actual name) which are basically potions or chemical reactions that repel specific creatures. It sounds silly—because it is—but the movie commits to the bit so hard that you just go along with it.
What Most People Get Wrong About the Ending
People think the defeat of the Grand Guignol is the end of the story. If you've read Ballarini’s books, you know it’s just the prologue.
The ending of the film shows a shadow. It hints at the other Monster Kings. There’s a whole hierarchy of nightmare entities that haven't been touched yet. The movie was clearly designed to be the first chapter of a franchise.

Kelly finally embraces her nickname, "Monster Girl." It’s a moment of self-acceptance. She spent the whole movie being embarrassed by her past—seeing a monster when she was five—and by the end, she realizes that her "trauma" was actually her initiation.
Practical Takeaways for Fans of the Genre
If you’re looking to dive deeper into this world or films like it, there are a few things you should actually do rather than just re-watching the movie on a loop.
- Read the Book Trilogy: Joe Ballarini’s books go into way more detail about the different "Orders" around the world. The movie only shows the Rhode Island/East Coast vibe. The books explain the European and Asian branches of the Babysitters.
- Look for the Easter Eggs: Rachel Talalay hid several nods to classic horror. Watch the scenes in the Grand Guignol’s lair again. The lighting and the props are heavy callbacks to German Expressionism and 80s creature features.
- Analyze the "Monster Science": The gadgets in the film aren't magic. They are presented as pseudo-science. If you're a fan of world-building, pay attention to the labels on the vials and the descriptions in the Guide. It’s all internally consistent.
The film stands as a solid entry in the "gateway horror" genre. It's for the kids who aren't quite ready for Stranger Things but are bored by Paw Patrol. It treats its audience like they are smart. It treats its monsters like they are actually dangerous.
To get the most out of the experience, compare the visual design of the Toadies to the descriptions in the first novel. You'll find that the film stayed surprisingly loyal to the "lumpy, gross, and slightly pathetic" aesthetic that Ballarini intended. If you want more, hunting down the second book, Beasts & Geeks, is the logical next step to see where Kelly’s training actually goes when the stakes move beyond just one night in October.
