The Sweet Gang is of almost no interest, except for its use of self-censorship for comic effect. Whenever a character is about to disrobe, the film is interrupted by a flashing "SENSOR !!!" [sic] warning. This happens several times, lasting from a few seconds to more than a minute, by which point the joke has worn rather thin.
A very similar device was used by Apichatpong Weerasethakul three years after The Sweet Gang. When Syndromes and a Century (แสงศตวรรษ) was censored in Thailand, Apichatpong replaced the cut sequences with silent, black footage to highlight the censorship.
