the game gets a bad rap from old school Zelda and Okami fans. But I am also an old school Zelda AND an Okami fan and I found the game enjoyable.
Yes the game borrowed many aspects from Okami, doesn't make it any less awesome. I would definitely suggest a rent. The game is surprisingly long and pretty fun [like every zelda game]. Between this and Ocarina of Time? I would still go with Ocarina solely because it had a better setting and story, but it doesn't make this game any less good.
