I like to watch Jesus films during Lent, so I took advantage of the fact that a new one was actually playing in the cinema this year. My review of Son of God can be found at the Third Way Cafe website (link below), but I should add something from my notes that didn't make it into my review:
If Son of God was meant to do more than make money (i.e. if it was meant to attract more than just Christian audiences), then my assessment is that it will be judged a failure. Reports from secular viewers would suggest (as does my review) that the film was not compelling enough or understandable enough to attract secular audiences.
