I'll say my peace and then I'll bounce.
As for Vergil, I found his DmC incarnation even more lame, with that sudden "change of heart" that anyone could see coming.
Sorry to say, but this just means you were really not paying attention to the things Vergil was actually doing in the game. Par for the course though, if you say that you yawned whenever he came onscreen. The sad part is that Vergil suffers from his character source being evil, so people expect him to "turn" at some point in DmC, out of tradition for that source material. However, Vergil
does do this (out of tradition) but people see he is "good" in the beginning of DmC, and constantly wait for that turn, without bothering to pay attention to the finer details of what Vergil is doing.
At the same time, however, this isn't to say that the hints were easily noticed, the evidence is there, but it requires those last moments of Vergil's "turn" to pain the rest of the picture. All throughout the game he makes some questionable choices that are written off as a man sacrificing things for the greater good, but in the end we see that those sacrifices were made incredibly willingly because he doesn't hold humans to high regard, and the only greater good he was concerned with was his own as a nephilim.
Also - you are succumbing incredibly easy to melodrama, something that Asian work is just
full of. It's very effective at making an audience feel something in the moment which is great for , but it doesn't last as long because it's all emotional idea, without enough emotional substance. You're right though, Lady shooting Arkham was very impactful, one of the only truly impactful moments in the classic franchise because it had tons of emotional substance, as is Dante reaching out to Vergil at the end of DMC3. Something like Credo's death, on the other hand, falls short because it's just a faithful servant dying at the hand of the leader he trusted. The melodrama can be entertaining, but that doesn't quite make it a high caliber of storytelling.
Okay, time to make like a fetus and head out of this topic.

On-topic, I sure am excited for that DmC-DE-! Very intrigued to see that new cutscene to see what they wanted to get in there. I know it won't be anything substantial, but I'm curious nonetheless.
