"I Know What You Did Last Summer" is a slicker-than-usual "Friday the 13th" rip-off, but not quite good enough, considering that it came from Kevin Williamson, who is breathing new life into the slasher genre with each life he snuffs out at his steaming word processor. In this case, the killing begins inadvertently, as four kids partying to begin the summer before they'll all scatter for college hit another kid while driving drunk. Panicking, seeing their bright lives destroyed, they dump the corpse into the nearby ocean.
