Well, they've always been criticized for not having a more romantic connection on the ice (and Charlie in particular is not known for his expressive acting). They're pushing it, and that's a good thing. According to an interview, they picked music that was only sung by Quasi or Esmeralda, avoiding music sung by the other male leads so that the story would be consistent (at least to those who know some French).
The problem is that they're using too many pieces of music. They need to take out one of the instrumentals and amp up Danse Mon Esmeralda. I felt the same way about V/M's latin SD music last year. The FD had more breathing room between cuts.
I think Charlie's expression emerged and remained more consistent, but overall it's not much more dramatic than their S&D or POTO, both of which worked very well for them. I think the biggest thing to wonder about is clearly not the PCS--D/W and V/M are basically neck-and-neck, with D/W slightly ahead in the FD and V/M slightly ahead in the SD, canceling each other out. It's the technical side that matters. And we know that D/W were getting hit in the post-Grand Prix season, except for WTT. The TES is the thing to watch, because that decides every match-up they have. And without Igor, if they can't pull it up over this season, that might be a red flag. We know that both teams, especially D/W, were known as technicians who owned level 4s like there was no other number. There's no reason they should suddenly lose their strength.
