I don't get the dislike for Kendrick on Mona Lisa...y'all really hated his feature that bad?

I mean..this sounded like TPAB era Kendrick when he really was experimenting vocally. Since the song is a concept record, with Kendrick playing the nikka that gets set up by Wayne's chick...he got into the character.
How are you supposed to sound when you come to a realization that the bytch you fukking with was playing you all along and is out to harm you?
Yeah Kendrick did over act it a lil and could had sounded more angry than a sad ass simp but overall I enjoyed the feature and song.
