There's been a lot of fan backlash towards what's been shown so far, but I don't really understand it. The only gripe I have is that the game is being developed predominantly by Ninja Theory, but Capcom is still lending some of the old Japanese DMC staff to aid Ninja Theory.
I think Dante looks pretty cool and the only difference is that he now looks like a teenager (this is a prequel) before his hair turned white. His attitude looks about the same, his voice sounds like Dante as we knew him, and I think his outfit looks like a cross between Tyler Durden meets classic Dante.
