Actually, I am thinking that the earlier the scene, the better the "acting". Hi-pan is great in the Defender mission (where he is very Lo-pan-ish) and not so good in the dragon alert thingy. Nighthawk (which I am guessing is newer) is horrible with his Christian Bale-ness and trying to make sending lackey heroes to do the dirty work while he gets evidence off of a computer is poor writing. I bet the newer ones are the devs and their friends doing the voices.
