Beginning is classic and quite ok premise, 3-4 first parts are really interesting. Character development is good and with fine progress.
Then starts problems, typical like screenwriters got lazy and starts copying all the classic. Internal strugle between one good and one bad / openly idiotic team.
There is zero military anywhere only some alien robots are only one to help defend. Military base but totally empty except first intro part.
Additionally when is problem no one report it, no one coming to help, no one care and all is careless.
Typical general who without any control is doing what ever he want, what was actually forbidden by some "mysterious never shown" superiors.
Animation is ok just as is mentioned in many cases very low FPS.
Teenagers running everything so it's obviously targeted to very young audience.
Not fully wasted time, just even monsters as animation had better structure and military feel than this.
Typical lazy hot mess netflix show. Lot of invested money and very low downspiraling quality on the end.
So from 8/10 at begining it moves to bare 4/10...
