SEASON PREMIERE: This is the 10th season for this competition reality series, which used to be one of the most inspirational and satisfying of the bunch – but even with a lackluster “all-star” round last year, has generated little excitement since moving to Lifetime. Part of it is the natural aging process of a series whose gimmicks have become repetitive, but part is that the contestants, of late, have shown less creativity as designers than narcissism as would-be TV divas. Perhaps for Season 10, Heidi Klum, Tim Gunn and the rest can revive things. But can they, in Gunn’s phrase, “make it work”? They try tonight, starting with a fashion show in Times Square.
