Hollywood may be a fun-house mirror, but it's still a mirror, and what emanates from it, either on screen or the pages of US Weekly, is a warped reflection of what passes as standard social decorum in these United States. Still, director David Cronenberg's "Maps to the Stars" -- which wallows in the excess of present-day Tinseltown (though Bruce Wagner's script dates back 20 years to his days as a chauffeur for the Beverly Hills Hotel) -- is in many ways more depressing than outrageous, because the more outrageous it gets, the more it feels like a program on E!
