Why does every "gay" movie seem so much the same? Gay life is enormously varied but you'd never know that from the movies about gay life, most of which rehash the same clichés of father-son angst and trite rites of"coming out." "Leather," whose title might lead viewers to think it's something it's not, is yet another film in that long, tiresome line. I suspect the filmmakers' hearts were in the right place. There are moments when you suspect something heartfelt and meaningful is going to happen in this rural tale of a New York City boy who falls in love with a boyhood friend who's morphed into an idealized woodsman - but the writing and acting and are so amateurish and the production work so slipshod the emotions of the film never gain traction.
