Troma's popularity waned after the box office failure of "Troma's War", a contributing factor to the company's collapse as a major film studio, forcing the Kaufman to eventually downsize his business into an independent film studio. Kaufman attributed the film's lack of success to cuts made to the movie after the MPAA refused to release it with an R-rating in its intended form. Troma's attempt to regain its popularity with the superhero satire "Sgt. Kabukiman N.Y.P.D." was unsuccessful, failing to make an impression at the box office. From 1995 to 2000, Kaufman retrofitted the studio into an independent film company, finding success amongst cult movie fans and critics with the independent film "Tromeo and Juliet" (1996), a loose parody of Shakespeare's play. Other independent films that followed were the less successful and poorly reviewed. "Terror Firmer" (1999), a slasher film set on the set of a Troma movie (with Kaufman playing a caricature of himself), and the fourth installment, "" which proved to be an ultimately unsuccessful revival of the series, both films failing to make an impression at the box office.
