TL;DR: Slow supernatural horror with strong acting and decent atmosphere, but uneven pacing and ideas that don’t fully come together - worth it for the performances, less so for everything else.
Plot
A woman puts everything on the line to defend her enigmatic cousin from a dangerous otherworldly entity determined to track him down.
Slow Rhythm That Tests Patience More Than It Should
So this one moves at a pace that really makes you aware of the runtime, and there are stretches where nothing much is happening, and instead of it feeling like tension is building, it sometimes feels like the film is sitting in place for a bit too long not really knowing what to do.
It’s weird because there are hints that it wants to be methodical and careful with how it unfolds everything, but it doesn’t always really feel as purposeful as it should, and while some scenes are pretty good, some come across as incredibly uneven.
Acting That Carries the Whole Thing Further Than the Script
Carla Gugino is really the anchor here, constantly trying to keep control of the situations that don’t behave properly, and what I liked is she doesn’t overplay anything, even when the film kind of invites a bigger reaction, but she manages to keeps everything steady, and that ends up making everything around her feel more believable than it probably should.
Lou Taylor Pucci is doing something much more volatile though, with a constant sense that his character is barely holding things together, so even when the writing doesn’t give him enough space, he still manages to make the performance work well enough.
Katherine Isabelle also shows up and instantly shifts the energy of every scene she’s in, and every time she appears, you end up paying more attention, even when you aren't fully convinced by what was happening around her.

Ideas That Are Interesting but Don’t Fully Land
There are some ideas here that I actually liked on paper, especially the way the film tries to connect emotional strain with something more unnatural pressing in around it, but the problem is, it doesn’t always develop those ideas in a way that feels complete - it hints, it circles, it suggests, but it rarely locks anything down, pun intended.
At times it also feels like the film is more interested in the concept of what it’s doing rather than fully committing to explaining or exploring it, and that can work if everything else is tight, but here it leaves a few gaps that you can’t really ignore.
There’s something strong underneath all this, but it never quite comes into full focus.
Horror Elements That Arrive Late and Don’t Fully Integrate
When the film does finally leans more into its horror side, it does pick up a bit, featuring moments that feel more direct, more intentional, and less like you're waiting for things to happen, but even then, it doesn’t fully connect back to what came before in a smooth way.
It's feels like the film changes direction partway through and expects you to adjust with it, but the earlier sections don’t really set that transition up cleanly.
Final Thoughts
Lockbox ends up as one of those films where I appreciated the effort overall, but everything just felt a bit uneven, with ideas that don’t fully settle, and while I won't say I regret watching it, but I also didn’t think it really nailed what it was aiming for.
