As a character, it comes off as trying too hard. Its not enough that he's super strong and isn't afraid of demons (and all that jazz), but he's also a rebel! And he has lots of Sex! And He's also hated by fox news! Previous DMC's sold us on Old Dante purely off his fighting abilities and his personality. There wasn't this need to use sex, rebellion and (although it was removed early on) smoking to sell him.
It just comes of as shallow interpretation of whats cool

I think the problem here is that there are too many kids who haven't seen or understand what a "cool" character is.
I mean lets face it, he has casual sex, smokes, looks like a druggy. Thats the essential 12 year olds version of "cool", as someone who is "rebellious"
But lets be honest, he's a loser. He lives in a trailer, he can't actually come up with a comeback(F*CK YOU), and even virgil/kat seem surprised at how childish and stupid he is. ---------------------
For all points and purposes, he's lame. He performs zero badass stunts in the cutscenes, he isn't witty, he's rather weak looking/acting to begin with, his confidence is shotty at best, and he can't even defend kat from cops, let alone demons.
But hey, I'm not surprised. People like Justin Bieber and all this other crap nowadays.
