Positives: nice graphics, sci-fi elements and depicted technologies are quite pleasing to see. Nice stuff with robots.

Negatives: sloppy writing: the plot is weak, characters are immune to dangers and at no point the viewer worries about them. Every problem has a plot twist out-of-nowhere solution.

Even the characters themselves are quite shallow. The true main characters are 2 kids, their mother and a con artist (first season only), the rest are supporting ones. The issue is that these characters are all Mary Sues, especially the eldest child, she has expertise at literally EVERYTHING at the age of 17.

Overall it's a great concept, but having a group of all-knowing immortals as main characters makes it boring.
