Open the Door (2023)

Door Lock has been a favourite of mine for many years. I'd say it's more of a subtle thriller, where as Don't Buy the Seller (or Target) is more action packed and in your face. I do prefer Door Lock but while watching DBTS I found I was never bored, and quite frankly it seemed like a faster paced version of Door Lock in many ways.

Both films are electrifying thrillers involving stalkers. In Midnight, the protagonist is a deaf woman who becomes the target of an evil killer who will do anything to catch her.

Both are about FLs having to deal with psychopaths who target the FL with obsession. They have similar vibes.

Definitely, with Shin Hye sun's great acting and the storyline. It's a pretty interesting watch if you're a fan of thriller genre.
