Spoiler
The movie spreads misinformation about Islam. The plot kicked off when a suicide bomber commited mass killings when he learnt that Barzakh is inevitable through a voice recording (?). Thus, to avoid the punishment, he commited suicide and killed innocents? Maybe the writers should study more on how to better convince the audience?
The movie tried to challenge morals and ideas of the audience throughout the movie as the main theme but failed to convey anything worthy of pondering. As if the writer had just went to watch a theater performance and decided to be a filmmaker the next day.
Not worth to call the movie a horror movie. Horror comedy? Perhaps. The movie was pretty good at establishing connections and setting up the story but it leads to absolutely nothing - only to goofy ahh creepy old guys and predictable jumpscares.
Plenty of other horror movies to watch out there. Save your 2 hours on something more useful.
