This is true. This is the weakest episode the show's had and it's really not able to write the whole religion/science debate that well (this is something Deep Space Nine and Battlestar Galactica both handled more coherently), and that the show seems to feel Lost-style conspiracy stories are a more valuable arc than stories about the relationships between aliens feels like a mistake. Defiance has a great premise and a good idea for an ensemble but it's not handling this all that well.
, as far as 'fantasy' goes, the French series The Returned
is getting rave reviews and premiering on UK TV on Channel 4 this Saturday.
