Because it's reinforced that that's not the kind of girl that gets the guy. I don't like the whole "well, she's an ass but so pretty and femme! give her the man-prize!"
There were two things up for grabs in this movie -- love and job satisfaction. IIRC, she came into it a good blacksmith and left a good blacksmith. How terribly boring.
Okay, fair point, at least on the annoying femme getting the man.
I do think the blacksmith gained something over the course of the movie though in terms of being able to do things on her own terms and get people to admit she did them well.
Competence is great, but I think her reward was negligible, and worse yet -- she's desexed.
I don't remember her as being desexed, just that she didn't happen to end up with William.
It has been a very long time since I've seen the movie though.
I think she should've ended up with Chaucer.
I have a feeling she ended up living in a mud hut with Mark Addy (and a few pigs).
I wasn't really invested in who William ended up with, but the way the story was told hit all the formulaic notes for the song that ends with him and Blacksmith Girl together. Him and Princess Chick together wasn't the right resolving chord for those notes.
I'm not even that picky about who she ended up with ... just that it's irritating to see the out-of-the-box chicks who wander off alone into the sunset after everyone else has picked up the love and career prizes. And when some of the everyone elses are not
good
epitomes of the gender stereotype, it makes it worse.
It's a thing.
I think she should have ended up with the pretty maidservant of the pretty femme ass, though I got the impression she was going to wind up with Roland.
Chaucer should end up with Wat.
I haven't even seen the damn thing, but, going by everyone's descriptions of her coolness and ass-kickingness and general overall worthiness, I'd vote for her ending up with Alan Tudyk, just on general principle.
