In a "Rolling Stone" review, Christopher Connelly described "Billie Jean" as a "lean, insistent funk number whose message couldn't be more blunt: 'She says I am the one/But the kid is not my son'". He added that the track was a "sad, almost mournful song, but a thumping resolve underlies [Jackson's] feelings". "Blender" stated that the song was "one of the most sonically eccentric, psychologically fraught, downright bizarre things ever to land on Top 40 radio". They added that it was "frighteningly stark, with a pulsing, cat-on-the-prowl bass figure, whip-crack downbeat and eerie multi-tracked vocals ricocheting in the vast spaces between keyboards and strings". Overall, the magazine described the track as "a five-minute-long nervous breakdown, set to a beat". "Stylus" said of the song, "It's one of the best representations of film noir in pop music, ending with no resolution except a single mother and selfish, careless scumball." In a review of "Thriller 25", AllMusic observed that "Billie Jean" was "startling" in its "futuristic funk". The track also won praise from Jackson biographers. Nelson George stated that Jerry Hey's string arrangement added danger to "Billie Jean", while J. Randy Taraborrelli added that it was "dark and sparse" by Quincy Jones' production standards.
