Yes, I went and saw the Grudge yesterday afternoon. It was thrillingly scary. What does that mean you ask? Have you seen The Ring? I give the Ring a ten in scariness. The Grudge was a close nine. Yes, that scary. It would have scored higher but the movie takes place in Japan and only in a certain house. The Ring is in the US and could happen anywhere. It's much more personal. I definitely recommend this movie if you would like to be scared OR if you want your female friends to be grabbing at your arms in fear. My friend Joe suggests going to the gym before hand.
For those of you who have already seen the movie: There's a little boy standing behind you.
