This is a weird one to rate, because it's not really even a horror movie. As another reviewer noted - it seems like the script forgot it's a scary movie for LARGE chunks of time. The acting seems to be bad on purpose and certain lines are delivered very accurately to the style of movie it's recreating. But the writing is just bad and downright boring for large chunks of time. It's most just people talking in various locations.
The visuals however do honestly make the movie worth watching if you can find it and like to see a time period media be accurately recreated. I can't say enough good things about the sets and decorations and costumes. They nailed it! Especially for a low budget indie movie - they def put a ton of work into that aspect.
However just about everything else is lacking. The deaths aren't that gory, the comedy isn't funny, the characters aren't interesting, etc. So overall it's not great but if it's free on a streaming app and you wanna see the 70s intruder and camo slasher be retold pretty well - including all their shortcomings - this may be the meh flick for you.
