If you could tolerate the movies, this is not that bad. It does start to dive into the weirder parts of the universe (the kaiju/jaeger combinations that showed up in the second movie).
There is a decent amount of action, but not as much as the trailer might lead you to believe.
7 episodes, 30 minutes each done in the modern cell shaded CGI anime style. Not great, not bad.
Voice acting is decent.
Biggest issue, it is an incomplete story that will be continued in the second season (both seasons were greenlit at the same time), Purely a money driven issue instead of story-based or audience -servicing.
you got time now? go ahead and watch. or just wait until the second season is released and binge the whole story.
edit to add: not younger kid friendly. Swearing and violence/gore (e.g., graphic headshot of a person, kaiju guts, etc)
