Amazing Race might have a billion Emmys, but all that glitters couldn’t deliver Friday ratings gold for the veteran reality show. The global race series had its 25th season premiere last night, having shifted from its longtime Sunday night NFL-assisted perch to the rough-and-tumble alleys of Friday night. Amazing Race returned to 5.5 million viewers and a mere 1.1 rating among adults 18-49. That’s down 45 percent from its Sunday premiere last season. Race led into downbeat returns of Hawaii Five-0 (8.9 million, 1.3) and Blue Bloods (10.6 million, 1.2), both slipping from last year.
