As long as you don't walk into the trap and try and tell it objectively when it blatantly isn't, I can respect that. The supporting cast of Juno were well drawn and developed and characters like Juno's dad & step-mum and Mark reminded of many people who I know; for that they seem real. Yes, it is true, there are people in the world who see the humour in their situation. As for the analogy of Ghandi and Ben-Hur, Juno is quirky in the same sense that both Bene-Hur is a drama and Ghandi, the man, was philosophical. It tries almost too hard to be the word I detest the most, quirky, but ultimately because the character just read off the page, it works.
Lars' script never quite dealt with creepy aspect of the doll being a sex doll. I can only assume they couldn't successfully deal with the subject.
