The first few minutes in, I didn't know what kind of movie this would be. But soon I quickly got engaged in how Joy and Grace got mixed up with a suspicious rich boss lady in a mansion- and the first half of the film the suspense was really good. Like watching a crime show. Then, the twists got even crazier on the later half when you can't even tell who the bad guy(or girl) is! Every 10 minutes I found myself rooting for a different character. It sort of reminded me a little of The Parasite, where a poor family moves in a rich family's home. All in all, the ending wraps up nicely and the last scene stays with you.
