An early entry in the '80s blood-n-guts slasher boom, the first Friday checks a broad number of boxes: gratuitous amounts of gore, hormone-driven teen victims, secluded setting, mysteriously prophetic locals... even a quick flash of skin. In many ways, it's also a bridge from the clunkier horror flicks of the preceding decade. The effects are often laughable, the acting is paper-thin and the production values seem extremely cheap and dated. Very few of the characters are even remotely likeable, either, which makes their relentless slaughter into something of a spectator sport. Once it ditches the vague premonitions and hammy teenage dialog that flood the first act, the film settles into a nice groove: stalk, scare, chase, kill, repeat. The mainstream success of Jason as a horror icon even gives this first entry a little boost, misleading first-time viewers into a surprise reveal at the climax (and, of course, an infamous jump-scare just before the credits). From a critical perspective it's not good, but lasting influence and dogged determination carry it a long way.
