If you'd like the entire plot explained to you, read the positive review in today's Utusan Malaysia. (If the link has trouble loading, you can read it here).
But if you don't like spoilers, don't read it lah.
I personally don't mind spoilers all that much. I have seen quite a few films including murder mysteries and The Sixth Sense after the endings were blabbed out to me, and I still enjoyed them. If anything, I felt like I was watching the films for the second time and noticing little clues.
