aberration

I reckon it's all an illusion created by the reservoir water ghosts to lure more people in and make them stay after the sunset. Whether you touch the stone and make a wish ,build or destroy stone tower ,does not actually matter for their survival - Yun Gi Tae is an example he arrived after the sunset , didn't touch the stone or a tower but was in the cursed area that ultimately led him to his demise .The legend is some urban tale spread on the internet in South Korea ,the reservoir exist in real life and people added to it some lore like water ghosts(Mul-gwi-shin ) ,GPS ,cursed land etc. I think that's why so many people attended theatres. But yes, the film doesn't explain much ,the storytelling is inconsistent.

there's a spin off serious about him if you are interested :Dong Jae, the Good or the Bastard

I will never ever stop adoring him. He is peak gorgeous .Pure talent. So natural and dynamic. Sadly, undervalued and underutilised . I would be casting him constantly .

Sadly disappointing . Marred with red herrings and inconsistent storytelling . This film generated such a hype that everyone expected masterpiece . In reality, it is just decent, nothing novel or extraordinary. Still, worth to watch for the cast and the atmosphere. Loved Kim Jun Han and Lee Jong won as Ki-tae.
