YMMV / Breaking Dawn

• Audience-Alienating Ending: The book is widely considered to be the Twilight series' worst installment, in large part because of how it concludes the story. The last three novels had been building up to the Cullen family battling the oppressive Volturi to survive. However, their final confrontation amounts to Aro, the Volturi leader, realizing Bella's daughter Renesmee does not threaten his rule, which prompts him to spare her and her family. In turn, the Cullens allow the Volturi to continue their rule over vampire society, despite previous installments showing their brutality and oppression of vampires and humans. Although the film adaptation attempts to address these complaints, it may have made the problem worse. While the film initially appears to provide the much-desired clash between the Cullens and the Volturi, it turns out to be a vision Alice shared with Aro to show what would happen should they fight. The film then proceeds to end in the same manner as the novel.
• Critic-Proof: While the franchise as a whole has this reputation, the book was contentious even among fans of the series. Nonetheless, the book still proceeded to sell loads of copies.
• Squick: Infamously, Jacob falls in love with a baby he is expected to help raise, and this is treated as natural and even romantic. There's obviously just so many things wrong with this concept that you wonder just how the hell Stephanie Meyer thought this was a good idea.
