Travis Lytle’s review published on Letterboxd:
Surprisingly polished, charming, and smart, Trish Sie's "The Sleepover" takes what could have been a throwaway action outing and turns it into something enjoyable. Revolving around a family whose youngest members learn that its matriarch may be a secret agent, the film find the kids and parents involved in perhaps-criminal intrigue. The story allows for comedy and combat, and Sie is able to blend the two while supporting the mix with genuine, family-friendly emotions. The kids may be more entertaining then their grownups, making parts of the work more engaging than others, but the entire experience works nicely.
