It's difficult to understand the claims that this new Hulk looks in any way "less human" than the 2003 version, especially in the context of that comparison shot a few posts above this one. It's likely simply trying to see something that isn't there. Their both big green guys with a basic human shape and features. Their physiques and proportions are a bit different, and their faces aren't exactly alike, but the differences are fairly negligible in regards to this argument.
Now, one difference that does stand out - though moreso in motion - and actually makes 2008 Hulk seem much more "human" than his 2003 counterpart, is the deliberateness of their actions and their facial expressions. 2003 Hulk was, for the most part, all reaction, no action. A feral beast with no real plan. The new Hulk is very much under control, very much the hero (essentally what Norton's Banner had planned on, according to the trailer) - he transforms, collects himself, engages in the obligatory good-guy/bad-guy stare down, flexes a bit so we know he's tough, and then he and Abomination start jogging towards one another, presumably to beat each other up or hug or something.
