The scenes after the credits roll completely ruined the ending of what would have been a really great movie!

Watched this with Indy as a Halloween movie.

First of all ... it's not a Halloween movie. It's at best a thriller with some gory bits thrown in.

Second of all ... it doesn't make a whole lot of sense. I suppose it's best not to try and think about time-travel movies too much because they rarely make sense - but this one was glaringly poor. Sometimes actions in the past would affect the present and sometimes they wouldn't ... for no apparent reason.

The story itself was quite promising and the transformation from poor trapped girl into a mental case was enjoyable.

Now ... I'd read the reviews on imdb that all said stop the film when the end credits appear. But my curiousity got the better of me and I let it run ... which confirmed that I should have stopped the film when the end credits appeared. The post-credit scenes are just stupid and confusing and helped to drag this film's score down a lot.

43/100.

Great and tense dual time thriller/horor (not the scary type), ruined by an illogical twist that comes after the credits start rolling. If you turn it off after the end credits start, you're in for a near perfect watch.

WARNING - SPOILER !!!

Why did the older Young-sook disappear mid killing older Seo-yeon in 2019 if she didn't die after the fall, as suggested in the midcredit's scene where she calls her younger self to warn and results in Seo-yeon's mother disappearing in 2019.
