I live in peranakan culture and i know that the Nusantara archipelago has a lot of culture including the assimilation of a lot of culture.
One thing that baffles me is the mismatch reality of how crowded singapore is and how it's potrayed in the series, which almost empty. The problem is that most horror movie does not really goes along with modern technology, its just makes all the mystery illogical.
Second, there's too many ghost that's not even in south east asia. For example Jikiniki is japanese. The chinese hopping vampires are not South east asian culture, and the lore itself does not match it. If you're bitten by a vampire, then you're become a vampire and you are mortally damaged by sunlight. In this case, the vampire immune to sunlight.
The dialogue is attrocious especially when they try to use Bahasa (indonesia/melayu) in the series. They speak even more rigid than a formal news anchor. And i "love" how they have no accent at all, makes it very "believable".
For example, Thai movies are making horror comedy, but they are still scary but funny as well. I don't know what genre is this series. It's not horror and it's definitely not comedy. More like, "look at me! I'm a diverse movie!"
And lastly!! I love it when they somehow can read ancient java/sunda script out of the blue.
