Just read the LA Times' review of Relapse. It was a pretty good review. It said while his flow, wordplay, etc is amazing ... he's trying to shock us, but it isn't really working. What made him work the first time was he said things nobody would believe they were hearing, but ppl now know where they stand on those issues, and he's just bringing the same old horrorcore issues that don't shock us as much.
It said that they thought the whole issue of rehabilitation hypocrisy in the album is what made it shine the most, and if he kept working on that, it would seem like he's growing into a new artist, but for now, he's still stuck trying to rekindle his SSLP and MMLP success.
The album is good, but it's nothing revolutionary.
