The pacing is pretty bad and there's hardly any gore, so if that's what you're after you won't find it here. That said, the gore is central enough to the premise that if you dislike gore then this film won't work for you either.
The filmmaking isn't bad - there's some nice parallel action and the cinematography is pretty good - but it's still not really sufficient to hold your attention. As horror films go it's okay, but the focus on romance make it seem more like drama than horror - drama bookended by pretty tame torture-porn.
I'd recommend watching it if you don't have much else to do and you like mediocre romance and implied violence. There are some plot twists which are pretty stupid to be honest, but at least they tried to do something original.
