As with other reviews, I absolutely agree this is a terrible movie but one of those that's worth watching if you want a bit of a laugh and don't want a movie that is going to make you think. Very predictable and a bit silly. Definitely one you can easily watch by yourself if you get scared easy as the effects are in no way scary. The jumpscares you expect to happen are disappointingly not scary at all. You will defo need subtitles for the actors who mumble but the sound levels aren't too bad with this one, apart from the loud music that plays every time the Djinn makes an appearance. This covers the dialogue completely.
If you want an easy watch with a few unintentionally funny bits, I'd recommend but it isn't a movie I'd ever waste time on again.
