So You Think You Can Dance, 7.30pm, Ten At last, the judges many people want to sock in the jaw can lay their venomous tongues to rest. It’s over. Yes, the American finale is here, and tonight someone is going to dance all the way to the bank with $ US250,000 ($ 268,000). Roll on the Aussie version, slated for 2008. Princesses, 8.30pm, World Movies A tale of friendship and love between two prostitutes struggling to survive on the streets of Madrid. There will be blood on the streets if I miss one nanosecond of this one, as Marg Downey used to say. Heroes, 9.30pm, Seven Even devoted fans of the first season of Heroes seem not so enamoured of the second. As the show is fast- tracked from the US, preview tapes are not generally available for reviewers here before the show goes to air. But our spies tell us that Peter ( Milo Ventimiglia, pictured) remembers one of his forgotten super- abilities, while Hiro and Kensei reach a final dramatic turn in their legendary journey to feudal Japan. JTV Live: Powderfinger Go AWOL, 11.25pm, ABC They may not have taken home any of those lethal- looking ARIA awards this year, but few who saw it will forget Powderfinger’s performance of Lost and Running on the night. Just in the nick of time, without much commentary at all, JTV Live fires up the band and lets the music speak for itself.
