It's utterly superb.

Heavenly Sword boasts the best single-player campaign experience since Resident Evil 4 -- and that makes it the best single-player experience this generation to date. Earning an aggregate review of 80 (metacritic.com), the game would have been in the mid or high 90s if not for it being incredibly short. About 6 hours short. Still, Heavenly Sword is an experience unmatched. Bottom line: play this game.
