Agree that Eli Stone was a great show and prematurely cancelled. But I wouldn't say that Zoey is a complete rip-off though there are similarities. For one, the cast of Zoey since their own versions of the songs and dance as well. And while Eli was yet another lawyer show, Zoey is set in a tech company. But Zoey is still a show we like a lot and I think some others would too - especially if they liked Eli Stone!
Never watched Eli Stone - but we like Zoey's as well - Mary Steenburgen pretty much rules (in everything)
