Meh.
I love Tupac, especially his earlier stuff but I wasn't crazy about Me Against the World or All Eyez on Me.
I wasn't the biggest fan of Me Against the World, but it was a good album.
All Eyez on Me was a great album, though. One of the better rap albums of the 90's, IMO.
Don't forget The Don Killuminati: The 7 Day Theory. Another fantastic album.
