I really enjoyed the first two seasons, then came third and suddenly the children are flawlessly brilliant and are more adult than the adults. You could make the actors 20 years older and the script still wouldn't be aligned with how people function under these 'close call' circumstances. I found the storyline condescending at times as it tries to navigate treating the pre-teen/teen protagonists as expertly competent alongside portraying young actresses as mature adults in cinematography, while the young boys are displayed as incompetent yet democratic (other than the main).
Season 3 jumps between locations quickly making any world building impossible as the characters can't respond to these environments believably, - inevitably everything new is taken for granted and assumed as already throughly understood by said genius children while the adults are used for comedic relief and a soppy time filler. 'Robot' is the most consistent character who keeps the story going forward. Acting overall seemed to fall, maybe because of the filming conditions after 2020 events?
