"Simply Amazing" received mostly positive reviews from music critics. Taj Rani of Billboard claimed that "Simply Amazing" is a result of an experiment where Shania Twain and the Backstreet Boys birthed a mainstream ballad," also noting that "Trey's seductive vocals bring a warm welcome into the pop realm." While calling it "a certified hit", Maz of MTV News noted that the song is "melodic and reminiscent of early Usher." In similar vein, Jon Caramanica of The New York Times wrote that the song "has the pop pomp of recent Usher hits." Ken Capobianco of The Boston Globe indicated that the song "might be the big crossover pop hit that exposes him to a whole new audience." Nathan S. of DJ Booth agreed, claiming that it "goes for that crossover appeal with an acoustic guitar-driven cut that Songz does his damnedest to make the kind of song just as likely to get played on VH1 as BET." While Richard, also of DJ Booth, praised its producers for "provid[ing] an appropriately sweeping backdrop for the artist’s heartfelt vocals."
Alex Macpherson of The Guardian felt that the song has an "anthemic pop chorus", while Glen Gamboa of Newsday described it as a "rockish anthem". Elysa Gardner of USA Today picked the song as one of the tracks on the album to "download" and website Rap-Up chose it as one of the publication's favorite tracks. While reviewing Chapter V, Lewis Corner of Digital Spy wrote that the song is a " mid-tempo ballad that will seduce many a swooning teenager." Robert Copsey, of the same publication, wrote a separate review of the song, analyzing that "it's not his strongest offering as he sings smitten about losing himself under the covers with his freshest catch over an all-too-familiar finger-snapping R&B beat," also noting that "it lacks the bite of recent cuts 'Bottoms Up' or 'Heart Attack'."
