I saw "Risen" with my Small Group at church. I liked it ... it was a great mix of "fact" (from the Bible!) and "fiction" (the story of Clavius). The fictional part was certainly plausible, in my opinion. I think the film's greatest strength is the potential for outreach it provides. Inviting non-churched friends to see it with you may open areas of dialogue and provide personalized witnessing opportunities.
