I don't find this question as interesting as another, related question: how well can an LDS artist create a not-good, not-evil character, one that occupies a middle ground of morality, one that is moral, immoral and amoral? And, to remove the artistic aspects of the question, how well can an average Mormon understand those that are moral, immoral and amoral?
Clearly, we are dealing with generalities here; the answer, I suspect, lies with the individual artist/Saint and the character/other person. However, I offer up two reasons why I am skeptical of the LDS skillz:
First: Details. Consider the movie Sideways. I loved this movie, but know of many people who don't. In any case, I found it to be one of the best representations of being drunk that I have seen in film. One scene in particular--the one where Miles calls his ex from the restaurant--so perfectly captured that drunk-but-not-yet-fall-down-drunk stage. Anyone could shoot a scene where the camera flails widely and the actor is stumbling all over the place and the sounds are muffled and slowed--but could someone who had never experienced a drunk (or a drink) get the details right? This problem is further exacerbated when it's applied to the details of an ethos and not just a setting.
Second: Many Mormons (and the Church itself) sees things in very black and white terms. This is not necessarily a bad or good thing from an eternal/salvational perspective, but it does pose some problems. I cannot believe that anybody would reasonably believe that "One drink will make you become an alcoholic" though I see that sentiment expressed in different terms, like "if it wasn't for the church, I'd be an alcoholic," said by one who has never taken a drink. It seems that one is either sober or an alcoholic and nothing shall exist in between.
Another example, the inspiration for this post, one that I have a particularly hard time stomaching: all non-mormon guys want is sex. Of course, I've talked about this topic on this site before. But on this post we get comments that again say this:
"Also, when it comes to guys who aren't members of the church, once they find out about the no sex thing they're pretty much not interested any more." (1)
"So yeah, non-mormon guys will ask you out and be interested in you, but surely you know they are only trying to sleep with you." (2)
I've said it before, but again: as a non-Mormon guy, I find this highly offensive because (1) it doesn't apply to me and (2) it doesn't apply to any of my non-Mormon male friends. In fact, I can think of no one (male or female) I know that I can definitively say that sex is their number one priority. Yes, sex is a factor in the equation, just like hair color and whether or not you think Poison is the best band ever. It's not a deal breaker. And anyone who thinks it is (or uses it as such) needs to get out more.
So, I'm a bit skeptical when it comes the ability to create a character beyond the black and the white. But more importantly, I worry how attitudes like this affect my relationships with the Mormons. I, a single, non-LDS, male in his twenties, have quite a few friends that are LDS single women. Do they think that I'm only after them because of some hope that they will sex me up? And when I meet a single LDS woman, should I even try to be friends with them since I am, apparently, only after sex?
So yeah, Mormon girls will ask you out and be interested in you, but surely you know they are only trying to convert you.
