In maternity clothing

There's a movie playing at the Tivoli Theater in the Loop of University City named JUNO, that's something about a 16 year old girl who gets pregnant. I say "something" because the review I read was really vague. Like, what about this movie is so good? Just because it has a teenager (although the actress herself is probably at least 18) wearing maternity clothing? Like that's something special. Of course, Brittney Spears' sister is just 16 and now pregnant, and that's considered big news.
