Based on the trailers I've been seeing for this movie, it seems like they're crossing Wizard of Oz with a very old Chinese fairy Tale called the Journey to the West where a Monk is chosen to travel to India in order to retrieve Buddhist Scriptures and on the way he runs into some less than likely companions/body-guards.
My expectations for this movie are the same for every other kug-fu movie. Decent acting, good story, and fight choreography that will rock your socks and make your girlfriend cream jeans.
