I couldn't get past episode 2. The line delivery is poor and continues to get worse. There's also no respect for timing, whether its a comedic or dramatic moment. Actors don't seem to know how to listen to their co-stars, react, and play off of one another — they're all standing around waiting until it's their turn to deliver a line, and they do so histrionically and in isolation. I understand that these actors are young and inexperienced, but I would have expected a director to provide small adjustments to delivery, or encourage experimentation of other modes, that would have helped mitigate some of these issues.
Overall it feels like an SNL skit more than a wholesome drama, and it results in something unbearably cringey to watch.
I had hoped that the CGI (the bending is admittedly impressive) would compensate for any shortcomings, but unfortunately this isn't the case here. You can immediately tell when there's an amateur choice of angle, strange editing, and bad green-screening (take a look at when the Kyoshi warriors first appear — the background is miscolored and moves strangely against the actors in the foreground), all of which come to distract from the actual viewing experience.
