So Amazin' received mixed reviews from music critics.
Metacritic gave the album a Metascore—a weighted average based on the impressions of a select 12 critical reviews—of 59, signifying mixed or average reviews. David Peisner of
Maxim gave the album three out of five stars and said that Milian's "talent is real", and commended her "silky and sassy" voice. He praised Cool & Dre's "badass" production, as well as "intoxicating" lead single "Say I". Clover Hope of
Billboard wrote that Milian tried to transform from "peppy pop sweetheart" to "sweet urban soulstress", but the album could not "pinpoint her true identity" and could "only [scratch] the surface of who she really is." Hope praised lead single, "Say I", describing it as "instantly rousing". Dan Gennoe of
Yahoo! Music UK said that the production by Cool & Dre ensured for "a cohesive whole, with a clear, unmistakable identity". He praised single "Say I", saying it "shimmies to a feisty ghetto strut and Shaft-sized orchestrals", as well as "Twisted", "Hot Boy" and "Just A Little Bit". He described
So Amazin as "almost the perfect R&B album", only missing "a couple of killer singles". Sal Cinquemani of
Slant Magazine wrote that while Milian claimed that she was "proudly displaying the various sides of her multifaceted personality", he felt that "only personality displayed on
So Amazin is that of her contemporaries and predecessors". He felt that contrary to the album's title, "
So Amazin proves to be anything but". Andy Kellman, of music database
AllMusic, felt that
So Amazin was "Milian's strongest album yet, if only by a narrow margin". He said that the album was short on ideas, with Cool & Dre using beats from some of their recent hits. He felt that Milian's weakness was ballads, which were "more like placeholders that merely apply some forced variety to the album"; but described the club tracks as "perfectly functional and appealing". Quentin B. Huff of
PopMatters praised the album, "despite a few lyrical hiccups, a couple of lackluster hooks, and some obvious influences." ==Track listing==
