It's a question of entertainment. The old Dante was entertaining because he was a cheese ball whereas, the argument goes, the new one is unlikable. The former was funny at best and stupid at worst whereas the new one creates an investment from the player. At best it makes the experience more enjoyable and at worst it aggravates the player, damaging the experience. I think that the Fallout vs Fallout 3 comparison is too extreme but it would seem like Team Ninja has some characters that are similar in some ways to Bethesda. There seems to be an attitude with the creative controllers that what came before is irrelevant and a mockery and dismissal of some of the elements that many of the fans liked. For Fallout the mockery was of the mechanics whereas DMC it was for the characters and tone of the game. This meant that instead of going back to the core of the characters and re-imagining them from there, they pretty much took the most general plot summary of DMC 1&3 and went from there, redesigning all of the characters from the ground up. It's a dangerous route to take because if you don't execute it well enough you'll get hammered for it.
