This is at least the second Chinese film I have seen lately that features at some point a massive heavenly Buddha intervening on Earth. It would seem that the government doesn't have a problem with such ideas being promulgated in cinema, which I suppose shows how technically communist states have moved on a bit.
I find something rather watchable about movies loosely based on the Monkey King story now. I'm even tempted to read the book. I knew someone once (an Australian but from an Asian family) whose secret ambition in life was to produce a movie that did proper justice to the book Journey to the West. He evidently has not achieved that.
Update: One thing about Buddhism - if a Catholic were to become one, the Mahayana version is surely the type to which he or she should feel more affinity (given the Communion of Saints idea is not a million miles away from bodhisattvas being able to help):
Mahayana Buddhism agrees with Theravada Buddhism that the human problem is suffering; it holds the Four Noble Truths as fundamental. But whereas Theravada holds out the ideal of the individual striving alone on the Eight-fold Path towards nirvana, Mahayana adds helpers who provide shortcuts and assistance out of compassion for those who are suffering. These helpers are called bodhisattvas, and are beings who have worked towards enlightenment and nirvana. But rather than enter nirvana, once they are able, they turn around and bring their store of wisdom, power and merit to help others along the same path. This simple idea has a number of ramifications for the goal of humanity.
