The atmosphere in Juno is quite extraordinary. It has this happy-go-lucky thing going that probably won't be appreciated by everyone. However if you like Ellen Page's character (Juno) then you'll probably like the movie. I enjoyed it immensely. The script is really well written, even though it sometimes feels like it's trying to be a bit 'too much' down with how teenagers speak to each other nowadays, or actually...how some people think teenagers talk today...
Anyway it's a real little indie gem. Highly recommended.
Not my type of movie, but this one has a certain charm to it. I think this might thanks to the girl playing Juno - Ellen Page.
