Why? He is cute, why is it so forbidden for the ladies to have something once in a while?
I don't think Martin Freeman is that bad-looking of a fellow, not to mention the fact that these movies also have Orlando Bloom, Lee Pace, and Luke Evans. Couple them with Cate Blanchett and Evangeline Lilly as the strong female characters, and there are enough attractive people in these films without this added distraction. Sorry if that makes me a harping purist, but that's what it is to me. This is an adaptation of Tolkien's work, and this is as un-Tolkien as you can get (albeit from a purely visual perspective).
But let's say Jackson's hands were tied, and Heartthrob Dwarf was a studio mandate. Here is Aidan Turner at the Hobbit press conference in February 2011:
Is he really suddenly that unattractive with the beard? You've got women tripping over themselves at the sight of Chris Emsworth in Thor Mode, yet this would have been unnacceptable? I mean, really? Since when were full beards so frowned upon by the female population?
Granted, I'd still prefer a longer beard than this (nitpicker, I know), but as far as choosing between the lesser of two evils, that right there is a vast improvement over what we got. Leaps and bounds. Because at least that right there holds true to the text - in that all dwarves (male and female) have beards since birth.
He grows an epic beard out for the press conference, then shaves it off two weeks later to play a Tolkien dwarf. Talk about a cruel joke.
