Needle Drop does great reviews most of the time. He's honestly one of the few really critical ears left out there who isn't just giving an artist a good/great score just because the artist has sold well a few times. And whether I agree with his reviews or not, I always walk away from them with two things: knowing that he took a definite stance with how he feels about the album, and that he explained his stance clearly. And I think he covers rap pretty well. Him being white has nothing to do with it.
All that said, this review was beneath him. If he didn't want to review it, he should've just not made the video. Don't make a video and act like you're above reviewing it if you're just going to clown; the album has gotten some decent reviews, and there are people who take his music, and him as a reviewer, seriously enough to warrant either a real review or nothing at all.
