I saw the movie Barely Lethal. This movie stars Hailee Steinfeld (Pitch Perfect 2), Dove Cameron (Liv & Maddie), Jessica Alba (Dark Angel), and Samuel L. Jackson (The Avengers).
A teenage special ops agent coveting a "normal" adolescence fakes her own death and enrolls in a suburban high school. She quickly learns that surviving the treacherous waters of high school is more challenging than international espionage.
I give this movie 2/5 stars. Watch the credits.
