Lots of complaining and low reviews because people don't like the family dynamics going on, but this is a family drama set in a scifi world. If there wasn't something constantly going wrong there wouldn't be a show, so I'm not sure why people are complaining about that either. The show is interesting, heartfelt at times and entertaining. The CGI is excellent, and once you get past the first few episodes where they're setting everything up, it starts really picking up.
