It is difficult question. As far as i can tell, religion for me is matter of trying rather than certainty. See, as much as he was trying to establish idyllic family and societal life, Joseph Smith was literally haunted by many, and he was mirred with family-related controversies. And yet, he came out with some fresh ideas, nevertheless, like Mormon version of creation, or temple based Mormon rituals, both of them still play important role in lives of millions of LDS church members. Some of whom do have harmonious family/societal lives exactly because they follow LDS church principles.
L. Ron Hubbard died alone, almost mad, and basically in the wilderness. He was unable to cure himself, and caused enourmous suffering to many of his followers. And yet, there are still prominent critics of Church of Scientology, who still follow some of Scientology, those so-called independent scientologists, right. So, some could claim that there is limited workability of Scientology.
Religion is strange proccess. Or strange art, which escape clear delimitations and definitions.
