The primary criticism I’ve seen in reviews of 'It Ends with Us' revolves around its portrayal of domestic abuse. Some readers feel the novel romanticizes abusive relationships by focusing too much on the emotional connection between Lily and Ryle, rather than fully condemning his actions. The book’s attempt to humanize Ryle, showing his struggles with mental health, has been divisive—some appreciate the complexity, while others argue it excuses his behavior. Additionally, the pacing feels rushed in parts, especially the resolution, which leaves key issues unresolved. For those who prefer a more nuanced exploration of similar themes, 'Big Little Lies' by Liane Moriarty offers a deeper dive into the complexities of abusive relationships.
