Insomnium (2017)

It looks like we're in for a fun time as we've a couple of friends inviting mischievous behavior into their lives and are not only doing it willingly but also laughingly. They seem like really close friends, and there are a lot of shenanigans from one of the guys that are really getting bizarre.
So, the character appears to be suffering from severe insomnia, but the sleep isn't sleeping at all, and it's getting weirder by the moment. If you don't mind the slow burn of the film, you may enjoy the storyline. It's so much more than it first appears, and in finding it entertaining.
What a truly fun climax to the film, and it actually caught me off guard, but in a good way. I hope other cinephiles give the film a chance, as it's not your typical horror flick, but it feels like the story has hidden depth to it.
