The album isn't bad at all, but Cole took a huge L because he made us believe that born sinner was the new mbdtf/gkmc/LR.
2 weeks ago I watched Wale campaign for fans to stop over looking the music being released today by he and his peers. He stated that we the fans are undervaluing the music being dropped today because we're still stuck on the Nas' Jay-zs' and Scarfaces' from Hip hops past.
A lot of artists proved that it was possible to get into that classic/legend debate as a new dude, ie:
Lupe Fiasco dropped Food & Liquor
Game dropped The Documentary
Kanye dropped college dropout
Jeezy dropped 101
Kendrick Lamar dropped Good Kid, Madd City
Big K.R.I.T. dropped his mixtapes
...
It's very subjective but all these guys came long after the 90's greats, a lot of them fell off a long time ago and only time will really tell the impact of these albums but all of them proved that it was possible to get into that classic debate as a new dude.
Even an artist like Drake is getting into that debate

So, where did Cole go wrong ?
"Let Nas go down".. "“I think me, Kendrick, and Drake need to stop acting like no one can do better than Jay, Ye, or Nas"
This album all in all sounded like Cole begging the Rap Gods for acceptance instead of just dropping a Classic album
Notice how its the Drakes, Coles and Big Sean types that are concerned with impressing their heroes and living out their "dreams". I aint mad, and Im glad that it means those kids didnt grow up poor on the street in crack-infested neighbourhoods. But its also extremely corny to me....just make your fucking music, seriously.
