Okay I'm two hours in:
Pros:
-Game is incredibly gorgeous, everything is highly detailed, from the environments, down to the clothing and objects in the world.
-The 4 knights are really well acted and written. The brief little cutscenes for small things like showing Gallahad crouching behind cover, or planning a sneak attack with your partner, really work (I realise now) because they keep you feeling like you're in a movie
-The controls and guns feel perfect
-If you've watched the long gameplay demo, the game feels like that so far. Once you're past the slow intro portion, everything moves along at a brisk pace and you don't want to stop playing or the game to end.
-THe knights' uniforms are really cool, particularly how they vary for different ranks
Cons:
-You can't switch shoulder views (left to right)
-During cutscenes, there's a slight stiffness in the characters' eyes. It's particularly noticeable in Igraine to me, for some reason, and also because the voice acting is so natural that it stands out.
