Larry Flick from Billboard described "So in Love with You" as a "vibrant disco ditty", noting that Duke "brings a friendly vibe to the song with a voice that is actually better suited to pop airwaves than underground dance-floors—though there's plenty here for club kids to nosh on".

[1] In October 1994, Mandi James from Melody Maker wrote, "The melancholic vocoder vocals and midnight hustle rhythms are on an almost Herbie Hancock tip.

"[4] A reviewer from Music Week's RM Dance Update said it is "a great track in its own right — lots of Latin flavour topped with Duke's cool vocals".

"[6] The magazine's James Hamilton declared it as a "simply marvellous Marvin Gaye/William DeVaughn-ish falsetto soulful European smash with a madly infectious summery humming 'la-la-la-la-la na' refrain".

[7] In 1997, another editor, Alan Jones, wrote, "Hopefully we'll catch on this time, since it's a funkily soulful groove, with a bassline reminiscent of Sub Sub's "Ain't No Use", elements of Freakpower's "Turn On..." and a sweet vocal not far removed from Marvin Gaye's "Got to Give It Up".
