Moria says, "Mimic does the basics rather well." 1000 Misspent Hours calls it "a monster yarn in the classic style, efficiently told". EW says, "A stylish B horror movie about giant insects in the catacombs of Manhattan, it’s by turns queasy, gross, terrifying, and — never underestimate this one — enthusiastically dumb." Roger Ebert gives it 3 1/2 out of 4 stars and says,
"Mimic'' is superior to most of its cousins, and has been stylishly directed by Guillermo Del Toro, whose visual sense adds a certain texture that makes everything scarier and more effective. It's not often that a movie like this can frighten me, but I was surprised at how effective "Mimic" is.Rotten Tomatoes has a 61% critics score.
