My feelings on him are quite mixed, but I can't honestly say I liked him all that much. He seems unable to grasp what it is to be an Assassin. He's incredibly niave and not the most intelligent man on the metaphorical block, two traits I wouldn't usually associate with the Assassin's. He never seems able to grasp that he's part of something far larger than himself, and sweet god do he do some things that annoy me!
I don't like. I don't hate him, either. I feel that he had all the ingredients for a great character, but the mixture wasn't right. The lack of emotion potrayed by the voice actor is also quite annoying. The stoic and reserved nature fits his people, but its taken too far, especially considering he spends so much time outside of his own people.
He just didn't click for me. Still, Assassin's Creed: Forsaken is coming in for review in the next few days, so I'm hoping that it can do what the couldn't and get me liking Connor.
