I think the multi-ethnic casting is great. My daughter who is 9 asked me if the Asian dude was really an angel. She asked me because all the depictions of angels she sees are Caucasians. Nice teaching moment.
As a side note I thought those angels kicking arse was great.
When Jesus next pays a visit the Revelation says he’ll have hair like sheep’s wool, and bronze feet! A few minutes work finding that description is worth your time ~ http://www.roadtohere.com/wp-content/uploads/2010/09/DSC_7365.jpg
