The storyline is actually pretty good and entertaining. I put it on out of curiosity and was pleasantly surprised. At first, I thought they were pushing it not allowing it to be just a movie. After completing the season, I now believe this would be a delight as a series. I love sci-fi and even though it's geared towards children, it really is a family show. The main characters JUST SO HAPPEN to be African American, but they don't make the show about that. That is refreshing to see!
The series is not slow paced and predictable as some kids shows are. I will say as a parent, these kids will annoy you a bit because THEY DONT LISTEN. But it's necessary to push the storyline forward. They grow on you as the season comes to an end though.
They aren't preachy so, you will have to explain that violence and misbehaving in real life have consequences. The things happening in the show are for entertainment purposes only! They don't sugar coat it because it's a kids show! Which makes it awesome sci-fi watching. I'd suggest it for kids 7 and up! When they fight, they FIGHT!
The graphics are movie quality. The storyline doesn't have any holes in it as far as season 1. There are no unanswered questions about anything. My only complaint is, I feel like the father doesn't react in a realistic way when the kids adamantly don't listen. Again, I think it's to push the storyline forward. If you watch bobs burgers he has very much so a "BOB" response! He never actually reprimands them for constantly undermining him, even though it puts them in serious danger. Other than that, I cannot wait for season 2. Netflix did a good job with this one!
