By Virginia Allen, The Daily Signal - I walked out of the theater surprised after viewing the new movie “Instant Family,” starring silver-screen heavyweights Mark Wahlberg and Rose Byrne as foster parents. It was not what I expected... The film features Wahlberg as Pete and Byrne as Ellie, an upper-middle-class married couple who decide on a whim to foster three children—Lita, Juan, and Lizzy—played by Julianna Gamiz, Gustavo Quiroz, and Isabela Moner.
