Definately worth a play-through.

User Rating: 8.5 | Heavenly Sword PS3
Just a blast to play. It really flexes the graphic muscle of the PS3. The cut scenes are well animated, facial expressions are spot on, voice acting is great. The three stance combo system really seems to deepen the combat with more options for how a person typically likes to play (close up, heavy hitter, distance). The aftertouch system is a good addition, although I would recommend turning off the motion sensing capabilities completely and controlling aftertouch (aerial combos too) w/ the stick.
It does tend to be a bit short, but so was Lord of the Rings: Return of the King and it was an awesome game.
All thing considered, a great addition to the PS3 library.
