School Killer (2001)

A group of friends decide to spend the weekend at an abandoned high school where five students were murdered twenty seven years ago.  As soon as they arrive strange things start to happen.  The front door slams shut behind them even though there is no wind.  Lights are seen in another part of the building even though there is no electricity. Music is heard and silhouettes are seen dancing in the windows.  Also the cover to the well is found open after it was closed.

When the group splits up to explore, one girl goes off alone and disappears, only to be found murdered in the other side of the building.  When the group panics, Ramon reveals that he has a reason for the trip which is unknown to the others, and which should get him a severe beating.

There is a lengthy flashback which covers the earlier murders.  It also answers the question if you run in terror out of an abandoned high school but your jeep wont' start and the tires have been slashed, should you blow it off and opt to go back into the abandoned creepy old high school?  No... no you shouldn't.

The film is subtitled. It's okay. Some parts are creepy, but the characters do some really stupid things, which I guess is requisite for horror movies.  The most noteworthy thing is Paul Naschy is in it.
