In his review for Allmusic, David Jeffries wrote: "Bring your lover and your playful side because Gemini is an aptly named loose and free bedroom winner from Brian McKnight [...] That's where the concessions to music of the moment stop, and while they're not at all unnecessary, the album really succeeds when McKnight wears all his singer, composer, musician, and producer hats at once and brews up something between Prince's self-titled release and a Sweetback album.

"[1] Chris Rizik from SoulTracks found that "Gemini is a fairly typical McKnight album that his many (primarily female) fans will adore.

As with his other CDs, there are a handful of excellent, well performed numbers [...] However, the lyrical mixed messages and groupie pandering leave me cold and prevent the album from reaching the level warranted by its solid musical foundation.

"[5] Sal Cinquemani from Slant felt that Gemini, the singer’s seventh album, begins on a high note, the intro showcasing McKnight’s old school Motown harmonies, but the rest of the disc resurrects previous trends, matching the singer’s aural NyQuil (his trademark honey-dipped vocals) with the mildest of R&B formulas and hooks that barely register.

"[3] PopMatters critics Jalylah Burrell wrote that "with Gemini, McKnight manages to escape the lure of his trend-conscious alter ego, another of the 30-plus entertainers who feel a need to justify their presence in a youth-obsessed market.
