Toy Story has multiple meanings. 
The special has received generally favorable reviews from critics, with a Metacritic score of 79% based on seven reviews.
Matt Roush of "TV Guide" said, "ABC's "Toy Story of Terror!"
is a delightful half-hour vignette of gags, action and self-empowerment, couching its never-give-up message in terrific non-stop entertainment."
Brian Lowry of "Variety" said, ""Toy Story of Terror!"
is about a quarter the length of the average animated feature, but everything else here could easily be mistaken for the bigscreen version, from the pacing and humor to Michael Giacchino’s score."
Rob Owen of "Pittsburgh Post-Gazette" said, "It’s a small adventure befitting the 30-minute running time but it’s also clever in the way it ultimately puts the “"Toy Story"” characters in a recognizable situation, which is similar to the big-screen movies."
Neil Genzlinger of "The New York Times" said, "Once the annual avalanche of Halloween-themed episodes, specials and movies overtakes TV, you probably don't expect to be using the word "charming" very often.
But charming perfectly describes one such entry, "Toy Story of Terror!""
Todd VanDerWerff of "The A.V.
Club" said, "The "Toy Story" franchise has always operated best with a note of existential panic, and there’s some of that here, but it feels like the special leans awfully hard on the films that gave rise to it."
Robert Lloyd of "Los Angeles Times" said, "Themes from earlier "Toy Story" movies are also recycled, which should bother no one.
Although Woody and Buzz get their screen time--with Jessie, they are the "Jules et Jim" of computer-animated cartoons about sentient playthings--it is the plucky cowgirl, facing her fears, whose story this is."
