Gaaaahhh, no! His voice acting is awful. I'm sorry if the actor is reading this but I won't lie about that. There is not even a shadow of sincerity in the way the part is played; it's completely artificial; I bet the actor didn't even understand what he was doing. Maybe he didn't have enough time to make the part fully his. Unless he wanted to depict a pompous Ulfric, in that case he did it pretty well.
