For such a strong cast, this film finds a way to keep the audience at arms length in what should be an incredibly personal story. While Woodley is convincing at a whimsical and angsty teen, her journey through the mysterious disappearance of her mother is never portrayed as a real mystery and the final twist is so disconnected that, by that point, you may just not care. It's not a total waste, but, considering the billing, we should expect more.
