This movie may require you to suspend your beliefs.You must believe: that a store clerks is pithy, that a teenager is even pithier, that parents are supportive of a teen pregnancy, that teens at school aren't cruel, that a teenage boy wants a meaningful relationship more than gratuitous sex, that a neurotic, uptight professional woman is good single mother material, that a man slow dancing with a teenager half his age isn't a predator, that people know when to enter and leave relationships, that teenage pregnancy has no long-term negative effects.If you believe, you will be rewarded with a sweet viewing experience. But a cynic might say it would be appropriate if Juno woke up at the end of the movie.
