Bloody Murder (2000)

Counselors arrive at Camp Placid Pines to prepare for the campers. Most of them are friends, but there is bad blood between a couple of guys who were on the football team together.

The first night they decide to play a game called Bloody Murder. The rules are simple. The person who is it hides while the rest of the players break up into groups to find him. Once found, whoever is it screams Bloody Murder and everyone must get back to home base before being tagged. If you're tagged, you're it.

There is a legend of a kid named Trever Moorhouse who supposedly wore a hockey mask and killed campers with a chainsaw. Some of the counselors are a little leary of running around the woods at night, but with peer pressure in force, they all decide to risk it. Later Jason scares Julie by pretending to be Trevor, complete with hockey mask and chainsaw.

The next day Jason has disappeared. The head counselor seems completely unconcerned about his missing counselor. In fact it takes several more counselors disappearing before he decides to do anything.

Some observations (besides the fact that the killer's appearance and location are right of out Friday the 13th):

1. Whitney can't swim. But Dean takes her out in a boat and dumps her overboard because he's a dick. Once she's safe, she is amazingly calm for someone who almost drowned.
2. Why is there bad blood between Brad and Jason? The explanation is that Brad was the last person Jason competed against before he blew out his knee. So nothing happened to cause this feud?!
3. Jason seems really immature, but there is nothing to show he has a history of violent behavior until someone mentions it.
4. There is an old guy named Henry who shows up out of nowhere and says they're all doomed.
5. The camp is said to be isolated with no one living near it. Yet later when someone asks if anyone has seen Henry lately, the response is that he's probably at his house over there.
6. The camp has Jarts with metal points.
7. Whitney goes to the kitchen and grabs a box labeled "Snack."
