In a word: ew.
Assassin’s Creed 3 strikes me as a game with a lot of different parts that have been developed in isolation with no consideration as to how they’re going to fit together into a coherent whole. The developers have just thrown a bunch of stuff at a wall without even bothering to look at it to see what sticks, and they definitely haven’t bothered cleaning up the stuff which didn’t; it’s still smeared all over the game, turning it into a sprawling and self-indulgent mess that flat-out ignores the useful lessons learned in Brotherhood and Revelations.
