Like a bad Onion article

Rating: 2/10 (18 January 2008)

When Onion, a site/publication dedicated to presenting the news satirically, focuses on a specific person or issue it succeeds. When it goes beyond that, unlike Jon Stewart and Stephen Colbert, it typically ends up sounding cynical and loses any sort of irony and comedy it otherwise had.
With Juno, we have pretty much the same thing. It attempts to mock everything and in doing so mocks itself and loses any sort of significant meaning it may have had.
In terms of pure entertainment, it loses most of its wit and humor and so alternates between annoying and boring, like a teen or teacher trying too hard to fit in. So, in short, it becomes a poser of a film.
