Can evangelical Christianity (or Christianity itself) be saved?

I recently came across this documentary about an attempt from an evangelical Christian to start an open conversation about belief. It’s trite, in a way, but refreshing in the way that the documentarian opens himself up to ridicule and abuse, in many ways, in order to start the conversation from an emotionally “flat” place.

PLEASE watch, visit the website, or if you have something which seems as open about starting a conversation about such a volatile topic…more resources would be welcome.

Is this a good start? Is anything a good start?
