Many criticisms were pointed towards the story, mainly that it was very unclear in messages, form, and age appeal. According to "The New York Times", "Kiddies [...] will be undiverted by the humdrum animation and a palette that mirrors the film's moral and meteorological gloom. Neither will they respond to a script (by Chris McKenna) that seems more focused on tickling movie-savvy adults [...] 'Igor' leaves us unmoved by its vertically challenged hero." "Exclaim!" summarized, " the journey is sloppy and uneven, with technical fouls aplenty. [...] It is difficult to determine what audience might have an appreciation for this, as the material will prove too dark for many youngsters and too insipid for elders." "Slant Magazine" writer Nick Schager concluded that it "feels chintzy and imitative, with kids unlikely to be seriously captivated by its bland hero and viewers over the age of five ultimately apt to relate only to Scamper (Steve Buscemi), an immortal rabbit desperate to commit suicide." "Dark Horizons" writer Garth Franklin wrote that its content was too little in amount for a full-length film. Some reviewers were turned off by its pacing; Franklin noted that its "characters run around in a manic rush and yet there's little 'action' to speak of," while Robert Abele of "Los Angeles Times" wrote the pacing issues came in its editing, camera movements, and line deliveries.
