If it's unique, it should make Google happy!
And almost everyone is rewriting original stuff. Success depends on how much nicer and uniquer you turn the original into. Do you think all those reviewers of amazon, for example, (outside the Amazon site and the reviews written there) have purchased, tested, and then taken the mighty effort to write a golden article about it, and then publish it, then do SEO to it and included with a ama aff link? Naaaaw, I don't think so. lol
