The two houses where the second half's action largely takes place don't offer the variety of, say, the isolated summer camp's various areas in Sean S. Cunningham's Friday the 13th, and the characters act a whole lot dumber than in Cunningham's picture -- after discovering bodies in one house with the slow-as-molasses-walking Myers in pursuit, Laurie foolishly puts herself and the two kids she's babysitting in jeopardy by forever knocking on the other house to be let in; and when Myers is supposedly dead after having already proved himself resilient to Laurie's defenses, she still opts to stay in the house after sending the kids out of it to contact the police.
Nor, despite its remarkable box-office returns, did Halloween ignite the giant wave of 1980s slasher films - it took another two years for the Halloween-tinged Friday the 13th to get that party started.
A self-consciously avowed knock-off of John Carpenter’s masterful nightmare Halloween (1978), Friday the 13th has always been a scorned and derided film, with its mixture of shallow characters, boogeyman clichés, and gory spectacle making it an easy target for middlebrow critics to tear to pieces while boisterous teenage audiences lapped it up and asked for seconds (and thirds, and fourths …).
Producer-director Sean S. Cunningham and screenwriter Victor Miller had a plan (and freely admit it): rip off John Carpenter's Halloween for a quick buck.
It doesn't have the merciless style of "Halloween," or the gnashing sadism of "Last House on the Left," or the sweaty lunacy of "Texas Chainsaw Massacre."
The original "Friday the 13th" is a skillful, if by-the-numbers, horror pic, its very existence resting upon the huge success of 1978's " Halloween ."
