The much-anticipated movie adaptation of a book widely considered unadaptable, On the Road debuted to hundreds of eager viewers at the 2012 Cannes Film Festival. So what are the critics saying about this cinematic take on the classic beat novel?

Despite praise for director Walter Salles, the screenwriter, and the actors, many felt the film missed the overall point of Jack Keruoac’s seminal tale of youth and self-discovery.

“You can’t help but wish that Salles and screenwriter Jose Rivera had focused less on the stories in the book and more on the story of the book,” said Indiewire’s James Rocchi. Derek Malcolm of the London Evening Standard also noted that Salles “struggles to give his story the strong dramatic line it requires.”

Adam Woodward of Little White Lies complained of the “narcissistic, shallow tendencies,” of the characters, and that even “K-Stew’s boobies” weren’t enough to make On the Road a memorable film.

The Guardian’s Peter Bradshaw was a bit kinder in his criticisms, saying the film had “a touching kind of sadness” but that he couldn’t shake its “tiresome glow of self-congratulation.”

Those are definitely some rough words! But is it enough to keep you from seeing On the Road (and Kristen Stewart’s sex scenes) when it hits theaters?
