Juno wasn't typical American "deadpan" humor, it was actually quite pretentious and relied on age-inappropriate wit from the teenage characters who shouldn't be educated enough to craft that type of paronomasia. I don't agree with adding more "romance," since it's a film about a pregnant teen, not a mature couple, since teens aren't really capable of romance anyway. Michael Cera did a great job and was the funniest part about the film, but Juno herself, unfortunately, suffered as a character due to dialogue that tried too hard to be witty.

Also, the soundtrack was far too indie/cutesy/saccharine; it was clear they tried a bit too hard to achieve cult-film status.
