One of the finest Christians I have ever known used to say, "Little is much when God is in it." And that applies to Biblical movies. They should not be judged as ordinary entertainments, because their subject matter sets them apart, a priori, so that the usual standards and the ordinary expectations must be set aside. In reading the reviews, I see how easily one can say poor production, poor scenery, poor this and that. But I would suggest another standard, perhaps the only standard by which a film about Biblical events or Early Christianity can be judged: Did it give you a sense of deeper fellowship with the subject matter, and with those whose Faith has borne witness down through the ages to even touch us here and now? If it does, then it is a success. If it does not, perhaps that is less the movie's fault than the viewer's. I have been fascinated by the Early Christians (myself being what you might call a late Christian) since I was twelve years old---over half a century. When I watched this, my worldly cares, even my medical affliction, seemed to fall away and I was able to enter into a sense of fellowship with my spiritual ancestors. On that basis, the film is a resounding success, and nothing else from the mundane world of film reviewing matters.
