Happy Halloween is directed by Brittany Greer and the cast includes Emma Reinagel, Aline O'Neill, Cameron Mabie, and Nathan Shelton.
TL;DR: A teen comes back to her hometown for a Halloween event and gets dragged into a string of killings tied to a past prank that ended in death - It takes ages to get going, but once it turns into a proper slasher it becomes slightly more engaging, even if it never really surprises.
Small Town Return and a Past Everyone Is Avoiding
The story in Happy Halloween follows a teenage girl who returns to her hometown after leaving under uncomfortable circumstances tied to something that happened years ago, where back then, a prank involving her friend group went wrong, a classmate ended up dead, and instead of facing it, everyone quietly split apart and tried to move on without ever really dealing with it.
Now she’s back just as the town is getting ready for a big Halloween celebration at the school - decorations are going up, people are pretending things are normal, and the same group she used to be close with is suddenly unavoidable again.
The Halloween backdrop does help a bit here, as it gives the town something to focus on while everything underneath is clearly unresolved, and while the film is certainly not reinventing anything, it still manages to give the opening a bit of atmosphere at least.

Teen Drama That Really Takes Its Time
This is the biggest problem I had with the film, as for this kind of film should be quite fast paced, but it manages to spend far too much focus on teenage relationships, old tensions, and slowly reintroducing the past incident through conversations that often circle the same points without really moving forward.
I get what it’s aiming for, it wants the emotional weight of the past to build up so the later violence matters more, but in practice, it drags, a lot, and there are multiple scenes where people nearly say something important, then back away from it, and after a while it just starts to repeat itself.
So you are just sat watching waiting and waiting for something to actually happen, and it’s not that the drama is badly done, it’s just stretched thin, like it’s trying to carry more of the film than it comfortably can.
There are moments where the past incident is revealed in small pieces that do work better though, so uou get a clearer sense of what actually happened and why everyone is still stuck in it, but those moments are spaced out too far apart to keep the early section actually engaging.
When It Finally Becomes a Slasher
Once the killings do finally start, the film does slightly improve and become a bit more engaging - the structure tightens up, people get separated, and the sense of danger finally becomes something active instead of just something being talked about.
The abduction sequences in particular are where it starts to feel more like a proper slasher, with characters being taken and moved into a hidden location, and the film leans into a more stylised approach with how the violence is presented.
There’s also a bit of messaging built into how the killer operates, using the victims and what happens to them to push the main character toward confronting the truth, and yes, it’s a bit obvious at times, but at least it keeps things moving instead of stalling out again on more teenage arguing.
Familiar Structure and Predictable Turns
Even when it’s working though, it never really escapes how familiar it all feels, with the structure being very standard for this kind of story most of the time - returning character with a buried past, friend group with unresolved guilt, masked killer tied to an old incident, escalation, final confrontation in a controlled location - and it all lands exactly where you expect it to, so the film doesn’t really twist its formula or play with expectations, it mostly just follows the path it sets out for itself.
Even the reveals are handled in a pretty straightforward way - nothing really shocks, and nothing really shifts the direction in a big way - it just steadily moves forward until it’s done.
I don't really have too much to say about the film, because I am sure you would have seen this type of film done a million times before, and nothing really stands out, it just plods along until the end.
Final Thoughts
There’s a half decent slasher in here somewhere, maybe, even if it isn't anything new, but it’s buried under a slow first half and a heavy reliance on familiar genre structure, and while it works a bit better once the killings begin, it just takes too long to get to that point, and by then it’s already spent a lot of its momentum.
