My initial reaction to Juno was a mixture of amusement and annoyance. As the movie went on I started to get drawn in and I ended up enjoying it a great deal.
Juno MacGuff (Ellen Page) is a 16-year-old goth girl whose major talent is making smart-ass remarks. (She must spend hours thinking of funny/insolent things to say and saves them up for the right moment.) She is also, due to a moment of total irresponsibility, pregnant. This comedy is about how she choses to deal with the situation.
And that’s about all that I can say without spoiling things, except that the movie turns out to be insightful and touching. Ellen Page is really, really good here, initially showing us a character who doesn’t seem particularly likable and gradually revealing her to be vulnerable, decent and brave.
