I watch this movie when boredom strikes, so I don't really mind the nonsense in this story. But at least, it's a good movie to watch when you are bored in your free time and have nothing to watch. The theory feels not that deep, but the plot twist kinda makes me go 'huh?' it's almost a cliff-hanger ending but fortunately they made a great ending. I don't think I will watch it again, because the story feels a little flat plain in my opinion. The actors express their characters so well, I don't really see any awkwardness from them.
