Well, since it was revived...didn't get the chance to comment before, since I was away, but I will now that it's brought up again.
I'm with you on the "forbidden love" thing. I never thought, "If Roger didn't have Mimi, he'd be with Mark." In warning, my opinion is severely different than it was a few months ago, but now I can see both sides of the coin. For me, it depends on who's playing Mark, completely. Roger is, as everyone said, straightER than Mark, but Mark's affection for Roger is kind of a subjective thing for me, subject both to interpretation by the actor and by the audience. It can be seen as a platonic love and worry, or it can be seen as...more. But I don't think either interpretation lessens the intensity of what he feels for Roger.
That being said, I REALLY hate it when fanfic writers kill off Mimi just so Roger and Mark can be together at last!! I like slash as much as the next person--well, probably more--hell, I've written it, but that's just SO contrived and annoying.
Okay, that was more like eight or ten cents worth of opinion. And now I must go stir my fudge.
