This is an extremely ambitious but well-written and well-acted sci-fi story. The key is that it is not just about weird goings-on but rather, what people might do under weird circumstances. The answers are touching and thought-provoking. There are drawbacks and potential drawbacks. The show is not over yet; we don't know what it will look like when it is over, but so far, very good. I wish they had a larger budget so they did not have to skimp on special effects. But then, like early X-Files episodes--which this most closely resembles, the show relies more on the viewers imagination than on special effects.
