I'm not saying the old Dante needs or deserves any defending either; like I've said often, Dante stopped being even tolerable by DMC3, but just aesthetically, a change in haircolor is the smallest change he's gone through from what's been shown. If he wasn't so utterly filthy and unkempt, he'd be immediately mistaken for the love child between Alex Mercer and Adam Lambert. Frankly, it's his only real plus so far, but I'll wait to see if it grows on me, because I'm not one to base my final opinion on a first impression, even with fictional characters.
But frankly, a slightly more grunge, nonchalant personality does sound like a decent change of pace from an immature snarky trash-talker the likes of which has been done more than enough in video games. Either way, it's only a matter of time before DMC purists come in all Godzilla 1998 style with the "D.I.N.O."s and nerdrage and the works.
