Whores on horses. Westerns changed a lot after John Wayne died. “Bad Girls” is a 1994 revenge/caper/western with brief glimpses of Drew Barrymore’s boobies. Madeleine Stowe plays a butt-kicking madam with a dark past who shares undertones of homoerotic chemistry with Mary Stuart Masterson (Where is the Skinemax remake when you need it?). Andie MacDowell plays herself. James Russo channels Tom Sizemore playing a psychopathic bandito (which would be a great name for a rock band). Robert Loggia gets whacked (Doesn’t he always?). There are big guns (besides Barrymore). And no, Dermot Mulroney is not the dude from “Grey’s Anatomy.”
