"Finally", according to Spence D. of IGN, would "on paper" seem to be a "flop", "just like her other attempts at serious sounding tunes" on "The Dutchess". He, however, stated that the song "actually works", mostly because Fergie "lets loose with her voice", showing that she has range and a "nice, warm set of pipes". He concluded by stating that while the song "may be at odds with her bangin' club persona", it is a "rich, introspective number" that showcases Fergie's "maturity and sincerity rather nicely". According to a reviewer from "Alloy", Fergie shines "without a trace" of hip hop, reggae, or rap, which proves that she does not need sexual lyrics or synth-produced dance beats to "show off her pipes". That same reviewer wrote that "Finally" is "the biggest surprise" on "The Dutchess".
