King Arthur: Legend of the Sword ★★

Part “Game of Thrones,” part “Snatch,” and almost all bad, Guy Ritchie’s “King Arthur: Legend of the Sword” is one of those generic blockbusters that has nothing to say and no idea how to say it. It’s not the worst film of 2017 — after all, Jude Law plays an evil wizard who sacrifices his wife to a three-headed sex kraken in the first 10 minutes — but it might just be the most unnecessary.

Things start intriguingly enough, as Ritchie opens with a prologue that promises to push this very familiar epic even further towards hard fantasy than any of its previous tellings — such is the dark magic of CGI. Launching us into a medieval world of men and mages, the film kicks off with a very video-gamey battle between the human army of King Uther (Eric Bana) and the enchanted forces of the evil wizard Mordred (it doesn’t matter). Uther is just a guy with a great head of hair, but Mordred is a sorcerer who can control massive elephant creatures with his mind. Of course, anyone who’s seen “Munich” should know that this is a much fairer fight than it first appears, and Uther is able to save the kingdom.
