Do anda think that Jennifer Lawrence is upset that most of the fan didn't think she was perfect for Katniss at first?

Maybe but she probably expected it because she read the buku before she even got the part & knows she is(was) blonde & that Katniss isn't so yeah. But I cinta her for Katniss

Well, most of her fan still might be upset until the movie actually begins.

a little,
but she can prove them wrong ..

I THINK THAT SHE WAS OT MAD JUST UPSET U NO
