Reviews are wildly mixed. Moria calls it "a big disappointment." DVD Talk says, "the movie still works quite well for what it is." HorrorNews.net says, "Halloween II is the second strongest film from the lot, only falling short of the impeccable original."
Roger Ebert opens with this: "It's a little sad to witness a fall from greatness, and that's what we get in “Halloween II.”" Rotten Tomatoes has a critics score of 29% but an audience score of 64%.
