Play Along Toys also created an Aaron Carter action figure in conjunction with the album's release.

AllMusic's Stephen Thomas Erlewine commended Carter's voice for sounding less childish but criticized his performance of kid-friendly songs with adolescent overtones and sexual themes, and the producers for utilizing "cut and paste commercialism" with various genres throughout the track listing, saying it comes across as "disturbing pandering";[1] he also described the album as "crass, a word that doesn't quite seem to apply, even after the deliberate repeated references to the Backstreet Boys (him and that Nick Carter, they're brothers, you know), until the album reaches its conclusion with an unlisted 11th track that is nothing more than young Aaron plugging a forthcoming home video and his songs for the Nickelodeon film Jimmy Neutron, taking the time to mention the release date for both the record and film, helpfully mentioning that the soundtrack includes songs not found on any other album.

[1] Beth Johnson from Entertainment Weekly said about the record, "Preteens across the country can rejoice: 13-year-old cutie-pie Aaron Carter has released his second sing-along album in less than a year.

Apparently A.C. (as he name-checks himself) knows what his fans like: cheery BSB/'N Sync-style raps, puppy-love ballads, and songs with "You" in the title (there are four of them).

Club awarded Oh Aaron the title of Least Essential Awkward Adolescence, with Stephen Thompson saying, "[A]ppearing to have aged about five years since 2000's Aaron's Party (Come Get It) and now possessing a voice that's gone from chirpy to unsure, the singer/rapper seems ill-suited for inching his way into artistic relevance as he begins to sprout facial hair and think about muscle cars.
