I've been playing some more (I think I finished level 7 now).
Dante is completely unmotivated and takes out quite a chunk of joy in playing the game, because I have no good cutscenes to look forward to. The only moments where I saw hints that Dante might be actually enjoying busting demon asses was when I was basically killing the Succubus boss which was kinda overshadowed by the pointless "Fuck you!" back and forth between Dante and the Succubus before the battle started. While that may have sounded funny while writing, a later second or at least third read should have made the writer facepalm himself.
The dialogue (and especially the one-liners) feels disconnected from what is actually happening in the cutscenes. They have a feel as if two different people wrote the scenario and the dialogue and then they just smashed it together. There is also another huge inconsistency in the game. While in the moving-picture parts of the cutscenes Dante seems to really have a raging motivation, it falls flat with the actual character. Dante's psychological profile is quite unreal. He is supposed to be a womanizer, but a person as unmotivated and as unengaged as that can't possibly be good with the ladies. He's a wallflower.
Remember the hints of depth that I mentioned from level 2? Yeah, they never happened. Dante doesn't know how to express himself and the connection between player and character suffers greatly because of that. I don't care about the new Dante. I wouldn't want to spend time with him, I wouldn't want him to be my friend, I don't look up to him, because he doesn't seem to have any desirable qualities whatsoever.
Even if I take out the original Dante from the equation, the new one is still boring. He's two-dimensional at best. That is, if he would express himself for a change instead of mumbling wanna-be badass one-liners which he doesn't even believe himself that they are funny. Dante, if you don't think your one-liners are funny, how do you expect me to find them funny? I think that the greatest problem is the lack of motivation, it's sucking out the life of everything around him, even undermining the depth of the other characters since everything seems to be centered around Dante, as if somebody is trying to say "LOOK AT DANTE! HE IS DANTE! BETTER THAN THE ORIGINAL! LOOOOOOOOOOOOK AT HIM! LOOOOOOOOOOOK!". Yeah, I get it. He is doesn't give a fuck about anything. He is too cool. He is a loner. Well, he can go fuck himself all by himself, because he's not going to get any pussy anytime soon, because he is too cool for sex. Not that he cares about sex, because he doesn't care about anything.
I would really like to say something good about the new Dante, I really want to, but I can't find ANYTHING. I really hope that things are going to change, because Dante's taking the fun out of his own game which, in gameplay, feels superior to its predecessors.
The battle against the Succubus was quite entertaining and fun (even though maybe too easy since I barely had to think or use actual play skill to defeat him, I didn't die even once). The levels are cleverly organized and even though they are actually linear, you get a feeling of vastness and the desire to explore every single corner. This obviously backfires since level score at the end is affected by how much time you need. Though, I still keep getting S ranks all the time for the time limit. Sure, I am playing on the "normal" difficulty, but I feel like I am getting quite a bit of undeserved praise.
EDIT: I was wrong, I finished level 6. And it seems that things start to look a lot better in the cutscenes at the beginning of level 7. Dante finally starts to feel like he has an actual personality. Let's see if he grows.
