Suspense is seldomly used in Indonesian Horror. The majority take the formula of "apparitions x100, then one last explanation at the end" to answer all the questions. Luckily, albeit the formula is still used partially in this movie, Soeriaatmadja doesn't make his horror debut full of jumpscares and employ a better plot.
What I like the most about the film, Soeriaatmadja knows that current streaming viewers have different taste in horror. He doesn't hurry to give everything, instead he unravels the mystery in chunks one at the time. This ride isn't perfect, since the story is quite simple and left a little to imagination. But, Raihaanun, the main female character, manages to act with the depth of her background with her appearances and perils.
Unfortunately, Raihaanun's character makes other characters (even his husband, whose supposed to be a child psychologist but looks like a workaholic-dad/jerk lol), feel too one-dimensional. Much of the characters seem to be a filler to stretch the duration without any importance to the plot. If you could overlook this, I think Affliction is a nice movie, though it's indifferent to others.
