It looks to be an intriguing watch at first, but after the first half everything went south. There's shock factor, but ummh there's so many questionable direction of the story. Like is Yusof death necessary? Like he got slain and the perp went to do what he set out to do??? There's also the weird thing of the main character being too unlikable (like major rude biash) that by the time everything got explained, you hardly felt sympathy for that character.
That's the plot problem. Acting is a bit stilted, the dialogues also felt weird and disjointed. And characterization is poor you cannot relate to the character.
This is one of the movie that has potential but falls flat due to poor execution. The plot point could have worked but they ruined it with illogical decision. Again, Yusof. Maybe if you have time to waste, watch it. Otherwise, go find other horror movies that doesn't disappoint.
