The ratings being low makes sense because the beginning wasn't too good tbh. Thanks to a comment below, I watched the whole thing and I like the stories and how they string few together or makes sense of almost everything by the end. The synopsis is all you need but the story is much more than what you'd typically expect from it.

The movie is almost like an anthology - but to be more precise, it's a group of stories all connected by a main theme - the ghost bride. Another review details on each short stories so I'm not getting into it.

Acting - was good and natural. Not much awkwardness.
Story - might not be hold your attention initially, but do watch in order. Once I finished the first 3 stories, especially at the 4th, it got my interest.
