There were some homages to game play, once the character changes disguises, there was another scene where 47 drags a body.
One thought I had while watching was that I fail miserably at times playing the game, so it would have been funny to see the character do a little failing, maybe some out takes during the credits. This was an entertaining action flick based on a video game. I did not expect much going in.
Ciaran Hinds' accent was terrible. I just do not like Zachary Quinto, I think it has to do with his performance in the Star Trek movies. Rupert Friend did a great job as 47. And the sister character by Hannah Ware was good too.
