This is a bad movie. Let’s get that out of the way.
First off, this film commits one of my least favorite filmmaking sins: spends half its time on just showing unlikeable people basically just hanging out. It’s not even bad pacing; there is no pace.
The acting is, of course, terrible.
In terms of plot, this plays like the mentally challenged cousin of “The Long Weekend”. Five high school friends, who don’t appear to like each other at all, reunite years later for a camping trip. They get lost in the woods and, one by one, suffer inexplicable deaths by misadventure, often from injuries that would seem to require a bandaid but in this film’s world are fatal: a woman stumbles and accidentally pierces her thigh with a branch, which turns out in a under a day to be a mortal wound; a few minutes of another woman sticking here fingers in a flowing stream in what looks like autumn weather results quickly in devastating frostbite, necessitating amputation; a woman dries herself with a leaf after peeing in the woods and apparently contracts Ebola from it; one girl simply wanders off and is soon found dead under a pile of leaves with no explanation; one woman is pursued by what is obviously stock footage of a bear. Within what seems like 36 hours the girls are starving and thirsty, and, of course, walking in any direction for too long brings them right back to where they started, because, movie. Meanwhile the bodies of other hikers, or sometimes just parts of bodies, turn up on the reg, without explanation.
But, you know what, it has some odd things that still made me like watching it, once it finally got going. What gore/body horror there is is pretty effective, shown only in extremely brief passing glimpses, but disturbing (and perhaps the only actually effective thing about this movie.) The fleetingly quick shot of the frostbitten fingers, for one, was unusually viscerally effective in such a poorly-made zero-budget movie. And once the action starts I found the weird combination of low-key and totally over-the-top amusing. And, it had a nod to that survival element that I always enjoy for some reason (cf. “Touching The Void”) and sometimes even predisposes me to notice the strong points of movies other people hated (cf. “Open Water”). This movies really only just barely has any of those good points at all, but, maybe, just a little.
BTW, I don’t do this often, but here’s a reviewer that didn’t enjoy it even the minimal amount that I did, and really does an effective job of tearing apart everything that’s wrong with it, in an entertaining enough manner to read: https://ravenousmonster.com/movies-tv/all-girls-weekend-movie-review/
