Very true, book fans will pick apart anything (and I'm not going to lie, I can put myself in that category as well
), including the green eyes. Though imo on the list of things to complain about when casting, for some reason eyes always seem to be the least important to me, unless they play an actual important role.
I feel like one problem with Jolene is they only put her in the show for her name. They though hey we'll get some more people to watch and they didn't really think about the casting. In a way I kind of feel bad for Jolene.
