Here's why she was cast and why her role is important:
* Continuation of the Relationship: Kunis played Lori in the original *Ted* (2012), and her character was a significant part of the film's narrative. Having her return was essential to continue the dynamic between Ted and his human girlfriend.
* Humor and Chemistry: Kunis and Mark Wahlberg (who plays John Bennett) have great comedic timing and on-screen chemistry. They play off each other well, making their scenes together both funny and heartwarming.
* Supporting the Main Narrative: Lori's role in *Ted 2* is to help Ted, who is now married to her, navigate the legal system as he fights for his rights as a sentient being. She is Ted's advocate and a source of support.
* Adding a Romantic Element: The relationship between Ted and Lori brings a touch of romance and human connection to the story, balancing the humor with a relatable element.
While *Ted 2* received mixed reviews, Mila Kunis' performance was generally praised. She brought a warmth and sincerity to the role of Lori, making her a sympathetic and relatable character even in the midst of a bizarre and comedic plot.
