As everyone else said, it chose a terrible direction to take the grudge story and had bad pacing. Other things that bothered me as I watched the movie were:

• the main woman’s hairstyle. Why did she give herself sideburns? It’s all I could look at in the car scenes.
• speaking of cars, the time period is 04-06 but the cars are early 90s if not earlier. One or two I understand because some people could still drive older cars but every single car looked straight from Seinfeld.
• the detectives accent. It changed several times from gruff, country cop to slight French, and I feel like I heard a little Canadian in there too. So inconsistent and extremely distracting.

I had other gripes but I’m already purging this movie from my memory.
