The core characters are believable as Mennonites, but casting Rosie Perez with what I think is supposed to be a southern accent is absurd. To hire Rosie Perez for any role is foolish because they all require something she doesn't have-acting talent. Aside from the fact that she can't act, her real voice is more annoying than the fake voice Fran Dresher used to when playing The Nanny. Even in roles where she is supposed to be "pretending" to be uneducated Bronx street trash, which is something that should be as easy for her as falling down she sucks because her natural voice is so annoying it seems unrealistic. Whoever told this woman she had a future as an actor must have been playing a cruel joke on her the way someone might evilly convince a mentally handicapped person that she could be Ms. America. As far as I'm concerned the joke has gone on far too long and her trying to do a southern accent is like watching that mentally handicapped person I mentioned before enter the talent competition as a break-dancer. Hollywood, please stop hiring this woman; she ruins everything she is in the way she has in Pure because her voice is like nails on a chalkboard and hearing it takes some viewers "out of the moment" and ruins the immersive experience of the story. They could save Pure by having Detective Bronco simply call the Texas police station where an actual actor tells his character that Detective Squeakydrawl was killed in the line of duty when she tried to speak to a suspect whose head exploded at the sound of her voice and she was caught in the blast radius. If you didn't give her lines it would be the best performace of her career, but her face would still ruin the scene because she looks like a squirrel (who can't act) pretending to be human while storing nuts in its mouth. For her to be cast in anything is ridiculous, but to hire her to attempt to play something other than an uneducated Bronxite who has a weird voice and can't act even with her native New York accent is a complete farce.
