I love it. It addresses all the problems I had with gkmc and adds so much more. He's able to pinpoint social issues so accurately and authentically that I'm able to see them from a perspective I haven't before.
I'm really picky with the hip-hop I listen to, and Kendrick's stuff thus far has been a little underwhelming for me, but this is some real shit. Whether it's a classic remains to be seen. But it's definitely a work of art - and that means a lot these days.
