Oh yeah, I finally saw The Grudge (the Japanese theatrical). After having the DVD sitting on my shelf for the better part of 2 years, I watched round by brother's place on Halloween.
Over-rated.
The concept was fine, but the execution just wasn't scary.
And the concept didn't really stretch out to the running time of the film. What was, I guess, meant to be an escalating sense of doom, became a chore as the house became something of a revolving door of death and flour covered kids.
I understand that there's plenty to ponder if you want to cogitate over the whys and wherefores of the thing if that's your bag, but the thing just don't do the scary thing on a visceral or a psychological level.
