According to Greta (PG-13, 2009)

Duff is by far the weakest link in this cast, and since she's the titular character, the movie ultimately falls flat. It's pretty disturbing when as a viewer you don't really care whether the protagonist offs herself or not; Greta is so unlikable and annoying that despite all of her narrated journal musings, she's so blase about suicide that you never once truly imagine her doing it. As Julie, Ross delivers a solid performance as the story's voice of reason, explaining to Greta that usually people who truly want to commit suicide just do it without necessarily informing everyone they know about their plans. Grandparents Burstyn and Murphy are such good actors, a much preferable movie would've switched the focus on their playful, still-passionate marriage as they deal with their off-putting, melodramatic granddaughter.

Melissa Leo cameos as Greta's mother, making it even more obvious how ACCORDING TO GRETA is like an unnecessary sequel to Georgia Rule (wild-child granddaughter -- check; stern but loving grandparents played by Academy Award winners -- check; well-heeled mother with husband troubles -- check). By the time the highly predictable, family-wide confrontation about Greta's dead father, her faux-suicidal tendencies, and her desperate need for structure and stability rolls around, it's hard not to imagine which former teen-star will tackle this exact role next. Amanda Bynes, don't do it!
