don't be dull, be fannish

When I suggest a threesome might be a more expedient solution to at least some of Peeta’s problems, [Josh Hutcherson who plays Peeta] immediately agrees: “I know Peeta would be into it, for sure. He’s very sensitive, in touch with his emotions. I think it really might solve a lot of their problems. You know what? I’m going to pitch that idea. Let’s make it a—what’s it called when three people are in a relationship together? A triad?” He rolls his eyes at his own enthusiasm. “That’ll go over well with Middle America.”

The Hollywood Reporter’s Todd McCarthy comments that Lawrence’s “lingering baby fat shows here.” And—most bluntly—Hollywood Elsewhere’s Jeffrey Wells calls Lawrence a “fairly tall, big-boned lady” who’s “too big” for Josh Hutcherson, who plays Katniss’s romantic interest. (In case the message didn’t come through: Wells thinks Jennifer Lawrence is BIG. He also thinks we should be wary of “certain female critics” who “may be susceptible to the lore of this young-female-adult-propelled franchise.”)

I agree that if the casting director were striving for pinpoint accuracy, JL wouldn't have been the first choice - but it's obvious by the selection of other actors that they really didn't care about physical accuracy.
Since that's the case - and pretty obvious - why aren't the critics pointing out the same misaligned casting issues with the other characters? Why is it just Katniss?
Stanley Tucci's skin was supposed to be blue and President Snow was supposed to look as plastic as a Ken doll, not old, wise, and bearded. And Woody Harrelson is just way too clean cut to be Hamich. He supposed to be one step up from cliche hobo-style guy.
So I think, yeah it is a little odd that it's female's body that under scrutiny (yes I know, she's the main character...but if a critic is going for accuracy, go for full accuracy!)
