...Yeah, I know neither are very healthy but Lotte lives in a happy little world where she views Raoul as a hero. And she forgets ONCE AGAIN Christine saved herself. Hello, Lotte please get an epiphany these days or listen to your freaking Faust tape and remember what your father told you.
I once attempted to write a fanfic - which was a crossover with Labyrinth, long story - where Raoul and Erik ended up being the same person, just showing different aspects. There were WAY too many similarities.
In the book? (especially in some of the alternate translations) Raoul is just as much of a stalker as Erik is. Christine only seems to be concerned about his stalking tendencies in terms of Erik finding out and killing him. We never said Christine was the shiniest crayon. We'll point out though that per the time (and a little before), Raoul's courting techniques weren't considered that strange - take a look at Les Mis and see how Marius stalks Cosette (and the two of them are the fluffiest couple EVER) to see it in play. If anything Raoul's less creepy then him.
On the Raoul side though - playboy doesn't count. Unless we're talking Yeston/Kopit. And I'm not sure on a superiority complex...unfortunately up here at the lake, I only have my "traditional" translation (i.e. the abridged which everyone is familiar with.) Way too annoying.
I've told people though, time and time again, the only way for Christine to truly be FREE and "WIN" is for her to not end up with either. (This is particularly true in the musical verse.) HOWEVER, per the times and the fact that CHRISTINE GENUINELY AND TRULY LOVED RAOUL. (Childhood sweethearts, come on.) it can be waved.
And on Erik's side, I'm not sure why "eccentric" is a bad thing. But that's just me. If you point again to the novel (that's the problem with these things, is this a book or musical venn diagram? idk.) Christine is mostly okay with the whole "...okay guy lives under the lake. That's his schtick, moving on with how to get OUT."
...and again, half of this is my opinion versus Lotte and Christine. Dear god guys, don't make me ramble on POTO-ness. I can do it for WAY too long.
