Xerxes sets out to control the major states of Greece with the help of his vast Persian army. Themistocles, the admiral of Athens, is forced to form an alliance with Sparta in order to save Athens. The film starts with droning exposition — explaining a plot that is historically inaccurate anyway — and adds wooden dialogue and stilted speeches. It may not court casual moviegoers as easily as its predecessor, but Murro succeeds at delivering a 300 sequel that fans will enjoy watching. 300, up to 11. The foot-in-mouth direlogue is an Achilles’ heel, but this campy gore-opera is bursting with guilty pleasures. See it large: the 3D is killer. They didn’t name it 600, but the Warner Bros. moviemakers certainly upped the ante in this double dose of hyper-stylized, 3-D sex, blood and guts.
