Personally, I liked VD.
It actually did something that DMC3 lazily didn't do; give Vergil closure. To see his character transition from the first time we see him as a calculated hacking man who wants to be the savior of the world from demons, to the power hungry tyrant who wants to have ultimate power and rule the world with his demon army.
It also showed Vergil's weakness that DMC3 didn't have the balls to show. It showed Vergil's internal struggle of always being second best to Dante. It can be said the same for DMC3. Vergil kind of did feel that he was always second to Dante, and that could even be said for the fanbase. When you see the DMC covers, who's always on the front, taking center stage? Vergil? No. It's either Dante or Nero. But where's Vergil? Oh yeah, he's just "second" best. third being Nero. Back to VD, it was through throwing away his emotions, casting out his heart of compassion and finally saying goodbye to his mother, killing Kat, and even killing his own brother, did he realize that he's going down a dark path that he can't escape now.
Just as DMC3 Vergil.
I am dissapointed that there was no BP for Vergil and no other weapons for him, but to me, it's story was what kept me happy, and that says a lot for me compared to just playing as him with no story of him, and going through the same old missions from before.
