Neither the first "slasher" movie, nor the most original, but John Carpenter's iconic scary movie was the first to tap into a the mainstream market, creating a lasting legacy and countless copycats.
The plot is simple and single-minded; a psychopath escapes from an asylum and spends the evening of October 31st killing teenagers and babysitters.
Style is very much over substance, with John Carpenter's eerie electronic score enough to send shivers down the spine alone, while the emotionless "face" of villain Michael Myers has also become part of horror folklore.

Virtual retread of the first movie, immediately following the events from the 1978 film, and mostly set inside the hospital where Laurie Strode (Jamie Lee Curtis) is recovering from the traumatic events.
The film wastes no time with any real development as it practically opened with the masked maniac Michael Myers killing random people indiscriminately and without real reason.
Jamie Lee Curtis & Donald Pleasance do a good job reprising their roles from the original film, but it does miss the directorial guidance of John Carpenter, even if he did stay on production as both producer and co-writer. A decent sequel, even if it does lie on top of the original film's blueprint. The Halloween series contained two years later, although the next sequel did not feature the same villain.

The title is a complete misnomer, since this has nothing to do with the two previous films and only makes reference to them in a blink-and-you'll-miss-it scene. 
The film itself is decent enough to stand on its own merits; a macabre scary movie about a satan-worshipping toy manufacturer who intends to restore Halloween to its witch-cult origins through masks which turn the wearer's insides into creepy-crawlies and goo.
An effective chiller, though original screenwriter wasn't impressed with the tampering of the evil toymaker character, originally inspired by Celtic myths and tradition, only to be reduced to a mad scientist.
Closer to Invasion Of The Body Snatchers than any other horror franchise and while effective, it does seem a little cheapened by TV movie production quality.

As the title suggests, the psychopathic maniac is back after 7 years (Michael Myers as the main villain was absent from the third movie), rising from a coma to continue his killing spree in the old neighbourhood of Haddonfield, Illinois.
Released 10 years after the original film, it's all rather formulaic and cliche-driven, and ends up being a step down from the first sequel with both plot and execution. Donald Pleasance reprises his role as Dr. Sam Loomis, but even he looks bored in this.
It's worth noting that this film marked John Carpenter abandoning the series and selling the rights to Moustapha Akkad & his production company, who wasted no time churning out Halloween 5: The Revenge of Michael Myers a year later, taking full advantage of the slasher craze which dominated horror movies of the 1980's.
