'Spell' is just 90 minutes of pure schlocky b-movie fun. They introduced some basic story elements at the beginning of the film, and I thought that this was going to be a basic occult horror film, probably mixed with psychological elements. But it's not.
At some point, they just drop the common sense and start having fun. If you're not new to movies you will catch the ending very fast, since the main lead literally explains the plot talking to the viewer (I was wondering why he wasn't looking at the camera). So you're just expecting more random and bizarre stuff to happen, and they deliver.
At times, the film felt more like a cheesy horror game but without jumpscares, the superhuman main character, zero realism, and people were driven not by motivation but by video game rules. Other times it felt like a weird combination of a horror-comedy, revenge film, Rambo sequel, and an 80ties TV-show.
I can't say I'd like to recommend this film, but if you love cheesy b-movie fun, gore, and intentional overacting (and you are prepared to switch-off your brain for 90 minutes) - you can give it a try. I can promise you - you will laugh a lot.
But if you try to take this seriously as a suspenseful occult horror film this clearly won't end up making your day better.
