Reasons why it stinked, stunk, and stank (spoilers)
1. Drowning a character in one body of water that is in close proximity to another body of water which is central to the plot. Too unclear and many were just waiting for the body to appear when the pond was drained. I've seen all the threads. She is staying at the castle when she returns to gather up his things and write the letter. She slips the letter under mommy-in-law's door so this much is obvious. That they were at a different body of water is not readily obvious.
2. Setting up a protagonist and then killing her off 1/3 in. Interesting idea, but kind of throws everything off.
3. Introducing a major character 1/3 in. I figured the doctor would be a throwaway character, but he slowly becomes the protagonist. Would have been better to throw him in earlier.
4. All of the dubbing.
Billy was only "thirteen" two months after it happened. Who would even SAY it like that?!
Who was it that tried to throw you in the pond? "Richard." Are you serious? So Billy's a ventriloquist now because his mouth didn't even come close to moving the proper way.
There was at least one more instance earlier in the film, but I can't remember it.
5. Too many cheap "scare" shots of things flying at the camera. Toy, owl, stroller. Very cheesy.
6. Showing too much info about the killer. Zero suspense. He was 13 two months later (Dementia 13), showing him with the ax, briefly showing the killer's face, flashbacks to the drowning, etc... It was just too obvious.
Now on the plus side:
1. The girls were pretty hot. Well, that's about it.
