BLACK RAT (2010)

Asuka, a quiet but upbeat high school girl who committed suicide by jumping off a roof wearing the oversized costume head of a rat she was supposed to dance in for a festival (yes, you read all that right) has seemingly come back from the dead when six of her fellow classmates each receives a text, telling them to meet her at their high school at midnight.  Once assembled, they're approached by a uniformed high school girl wearing the bloodied rat's head, who tells them via a notebook hanging from her neck that each of them will be killed to avenge Asuka's death.  The classmates are all stereotypes (the brain, the moron, the slutty cheerleader, the rebel, etc.), action fairly gore-free, flashbacks attempting to get you to know the characters only mildly successful - yet for a low-budget Japanese slasher flick with little slashing, with a "surprise" ending that only somewhat works, there's something curiously intriguing about how this film lays everything out, and its sheer goofiness.  Worth a look if you like this kind of thing.
