You can’t really say this dragon tale is an imaginative fantasy film – there’s hardly an element in it that hasn’t been lifted from the Star Wars or Lord of the Rings movies – yet at least the picture has intricately realized its derivative universe. Eragon is a rip-off, but it doesn’t look like one. Based on the best-selling novel by Christopher Paolini, the movie centers on a farm boy (Ed Speleers) and his dragon, who are drawn into a battle between rebel forces and an evil king (John Malkovich). With Jeremy Irons in the Obi-Wan Kenobi role.
