This re-envisioning of the classic character, probably made the most popular through the three Ray Harryhausen movies, is a completely different take on the character. In this show he's a young man who lives on the street of Bagdad, fighting and thieving to make a living. His brother is his sidekick. One day he gets in a betting fight with a guy who turns out to be the nephew of the King, the son of an evil guy named Akbari. The nephew is killed when he tries to kill Sinbad--and that's when things start to go bad. Akbari kills Sinbad's brother in revenge and when Sinbad goes home his grandmother puts a curse on him--he can only set foot on land for 24 hours or he'll die. So he has to go off on a ship. Which is when his adventures start. Akbari (Naveen Andrews of Lost) uses a witch to keep tabs on Sinbad. But Sinbad has plenty of troubles of his own, from encountering a Queen of Thieves who has a pet Roc (the giant bird), other dimensional gamblers, et cetera.
This show didn't quite do it for me. It's along the lines of Merlin (which I liked) and Hercules: The Legendary Journeys (which I didn't like).
