I've seen this movie out of the corner of my eye on my laptop many times. Spider-Man 3 and Dark Knight as well. So I have lots of opinions about Juno. Here's what I liked.
1) Alison Janney's character was the best concept in the script. The idea that she's disrespected and regarded as ineffectual and a nuisance until the 日 there's actually something going on that she should be on the ball for. And damned if she is. What a nice metaphor for what Moniq was saying.
2) Juno's friend is so fine. Honest to blog.
3) The storyline with the Lorings fit in no other movie except Juno. A major strength...
