I'm not used to reviewing films, especially since I'm aware of the limitations in Indonesian cinema, which often lacks detail. It's rare to find a film that makes sense from start to finish.

However, I feel compelled to comment on this movie because everything about it is really disappointing. It's a shame, as the individual performances of the cast aren't bad, and the message about balancing nature and the economy is strong and relevant. Plus, with Rizal Mantovani involved, you'd expect better visual quality. Unfortunately, the script is terribly flawed-it's hard to find a worse one.

Hence it is out of mind with Netflix recommend this movie as if Netflix does not understand how the brain cells work.

1. The mix of fact and fiction makes the story very difficult to follow. Sangkara is mentioned in connection with Jakarta and Solo, implying it's based on some "fact." If it's fact that it's a six-hour train ride in Java, that means it crosses provincial lines. So, the starting point of the station and the resort are in different cities and most likely provinces. How could one regent be responsible for such a large project? It makes more sense in papua or Kalimantan. So If Sangkara is a city nearby Solo 6 hrs ride might bring you somewhere in Nganjuk (east) or Tasikmalaya (west).

2. Trains are not like airplanes; they can STOP. It feels as if this were an airplane that can't make sudden stops.

3. The abrupt detachment of the train should create a significant sound impact. If the screenwriter understood basic physics, they'd know that the last carriage detaching would result in a strong collision with the carriage in front. We call it "momentum" at your elementary Physics. It is not like you pee and you dont feel anything.

4. The awkwardness of the characters knowing the train was detached repeatedly is hard to watch.

5. So, who is Tekun? A waiter and a train mechanic?

6. The random Dutch dance scene in the VIP carriage is completely out of place.

7. The subplot with a couple of thieves in the VIP carriage feels extremely disconnected.

8. If the train goes to resort, what business are belonged to those in economy? It is like a Noah Ark that bring anyone...

Everything about this film is disappointing.

This is a very sadistic film, so every time you go through a tunnel with red lights, one of the carriages disappears one-by-one, this is due to a crucial demon crushes brains out, mind controlling and manipulative sadistic colleagues to each passengers on board the climax started in the second ¾ act and it's beautiful CG to the ground. When every passengers crushed, only one cancer passenger survived, Purnama (Hana Malassan). The other thing is that by the third act, first the passengers were crushed their brains, then they death becomes a planet and grows to a tree. The reason that this devil was angry is that his house was being disturbed by evil humans who wanted to destroy his house for the sake of the railroad ?? Purnama would of said "her husband died already." The biggest idiot of this film was one character BARA (Kiki Narendra) yes he supposed to be arrested after but he was killed instead of held accountable. Overall, good experience of Indonesia film, this is probably my second time watching an Indonesia Horror film that has CG, first being Pemukiman Setan (The Devils Lair) Those 2 Indonesia film's do not have a U. S release date at all.
