“Laggies” is far from innovative, but it’s pleasant enough, and I think that’s the fitting adjective for this coming of age film starring Keira Knightley, Chloe Grace Moretz and Sam Rockwell. Knightley plays Megan, a 20 something woman who is still trying to figure out what to do with her life. When she discovers her father is having an affair and her long time boyfriend proposes marriage, she freaks out and retreats from her life. Then she meets Annika (Chloe Grace Moretz) a teenager with problems of her own. After a night of bonding, Megan convinces Annika to let her stay with her for a week in order to rediscover herself. If you don’t respond to these characters, or empathize with their situation, you’ll have little patience with the story. If, on the other hand, you develop a rooting interest for them to straighten out their complicated lives, you’ll enjoy this little film, a mix of comedy and drama. What’s more, Knightley has never been more likable onscreen, and the film is peppered with a solid supporting cast featuring Sam Rockwell, Ellie Kemper and Jeff Garlin. “Laggies” was directed by Lynn Shelton and written by Andrea Siegel. By keeping their goals modest they may not have created something original, but I found it diverting and enjoyable. Sometimes, that’s good enough.
