Moria calls it a classic. 1000 Misspent Hours gives it a good review and says, "The really remarkable thing about Halloween is that virtually alone in the subgenre it did so much to establish, it has managed to earn and retain the respect of mainstream movie critics." TimeOut calls it "A superb essay in Hitchcockian suspense". HorrorNews.net loves it.
Roger Ebert gives it a positive review that opens with this:
“Halloween” is an absolutely merciless thriller, a movie so violent and scary that, yes, I would compare it to “Psycho” (1960). It's a terrifying and creepy film about what one of the characters calls Evil Personified.DVD Talk says, "Halloween still works with an audience." Rotten Tomatoes has a critics rating of 92%.
