Here is an excerpt from Jill Stanek's review:
Juno is the third in an unplanned movie trilogy, the others being Waitress and Knocked Up, where a girl accidentally gets pregnant and grows into a heroine by rejecting abortion as a quick solution.
Social conservatives attempting to break through in movies have not yet mastered the art of getting our point across without coming off preachy.
But it's fascinating to watch the Hollywood and Indie crowd handle one of our premises pretty much the way we'd like it handled....
And here's Juno's premise, by movie reviewer Matthew Turner:
Engaging, frequently hilarious teen comedy with a terrific script, a wonderful cast and a delightful central performance from rising star Ellen Page.
Ellen Page stars as brainy 16-year-old Juno MacGuff, who gets pregnant the first time she has sex with fellow virgin Paulie Bleeker (Michael Cera). Unable to go through with an abortion, Juno decides to give the baby up for adoption, so she finds childless couple Mark and Vanessa (Jason Bateman and Jennifer Garner) through the want ads.
However, as Juno spends more time with Mark and Vanessa, she realises that their marriage isn't quite as picture-perfect as it first appeared. Meanwhile, Juno's father (J.K. Simmons), stepmother (Allison Janney) and best friend Leah (Olivia Thirlby) offer as much help as they can.
