If Joe used a great turn of phrase that you want to have in your review, make it a direct quote and credit Joe. But 4 paragraphs of text (as in your example) is going overboard. Long before you reached 4 paragraphs, you'd be at the stage where you'd be better off simply linking to Joe's review. Think in terms of a phrase or two (ones that are so good you want to credit the source), not in terms of paragraphs.
