You have to just accept the kind of campy look to the show, as well as some of the more questionable acting and dialogue choices. Once you just accept that this will be the presentation, you can focus on the story, which is very insightful and complex. At its heart it’s a political drama about American intervention in the Arab-Israeli conflict (never explicitly stated, but it’s pretty evident almost immediately), with a shadowy outside threat, presented through a sci-fi lens. Then it adds way more mysticism and fantasy elements as the series progresses. It’s a fantastic exploration of human nature, I strongly recommend it.
