Depends on what aspect of the religion you're looking at.
The JWs and smaller fundamentalist sects are different in that they try to seperate themselves from normal society. They're more cult than religion. The Mormons are cultish in a lot of their practices, though they don't shun society as much.
But, to me, all religion is superstition. Superstitious belief in a mythical being or beings, superstitious belief that by being in a particular religion and by observing their rituals that somehow you're going to prosper above all other people who don't hold the same superstitions. The history of the world is full of examples.
I'd love to travel into the future 5000 years and see how people then will talk about how their ancestors believed in these mythological creatures much like we look back at the Romans and Greeks now and talk about how they believed in the gods of their time.
