Well, first off you have to look at the source material. In the original novel, the characters were all pretty "blah" and almost to the point of really corny (and some characters went beyond corny) but the unabashed romantic element was prevalent throughout and there was no apology for it. Yes, some of the plot was, in many places, were filled with "WHAT?!?" moments, but again . . . it was unapologetic in it's romantic thinking. I think Webber and Prince captured this very well and even made improvements over the original source material by giving Erik a voice of his own and made you really believe that he loved Christine and would do anything to have her.
The problem with Yeston's version, is that it
COMPLETELY changed the plot to give it more of a back story to why Erik was the way he was and what brought Christine to the Opera house, but in doing that, it ruined the unforgiving romanticism of the novel. To me, the mystery of Erik was taken away and Christine was so stale of a character (I am only going by the cast recording since I have never seen the show) and Carlotta was even more of a corny character than she ever was in the ALW version. And I wouldn't have a problem with a back story of Erik if it was done right and stuck close to the original plot of the novel, but like I said before, it goes in a completely different (and I think) wrong direction.
People complain about the lushness and the spectacle of the ALW version . . . well guess what folks, that is how it is portrayed in the novel. The Chandelier falling is a
VITAL moment in both the novel and the show and people act like it was something stuck in the ALW version to make it more special effect oriented.
Both have it's problems and I am in NO WAY saying that the ALW version is a perfect representation of the novel, but it is a lot closer than the Yeston version and that is my biggest gripe above all else.
