Well, let's see some of the positions the movie takes:
1. Irony and snark won't pull you through; commitment and love will.
2. A real strong dad who finds satisfaction in his wife and children is better to have around than a hip, sexy guy who still dreams of the vie boheme and resents his bougie wife.
3. At 17, "You're the coolest person I know" is a compliment. At 37, "Aren't you the cool one" is a well deserved expression of contempt.
4. Whatever you do about it, pregnancy has consequences.
5. After all the cards have been shuffled, we still wind up with a deserted single mom who loves her baby.
Underneath the glib dialog, hip name checks and calm acceptance that teenagers actually have sex lives, Juno is a profoundly conservative celebration of traditional family values and an attack on bohemian self indulgence. I suspect that there are a lot of people who find themselves insulted by it.
