Well, I stuck with BSG until the end, but didn't really enjoy it after the first couple seasons. I don't mind it being serious, at all... there's just something about this movie that does some things "just because" it could. An example was the scene where he had just escaped, and was trying to order food in that restaurant. The alert came on, about the escapee from the medical isolation ward; now, that already had the people freaked out, and backing away from him. But, then, they have to show a crappy photoshopped pic of him doing an alien, and says he's wanted for having sex with aliens. That doesn't seem like it's taking itself very seriously, to me.
Well, given that they really
want this guy back before he turns into a Prawn, and the story he'd be telling to people would be "so-ridiculous-that-he's-gotta-be-telling-the-truth," what better way to disgust and frighten people than to say that he fucks aliens, especially on such short notice?
