His characterization is so inconsistent. You just don't know what his personality is. Is he the prankster? The Cool Black Guy? The quirky roommate?

Jess = Adorkable, hopeless romantic
Nick = Manchild, who underachieves and is afraid of commitment
Schmidt = Reformed Fat Boy who can be a little too self aware douche but has a sensitive side
Wintons = ????

I've seen Lamorne Morris in some Funny or Die videos and dude is hilarious! He really needs better material to shine. "New Girl" is wasting him IMO.
