So I have an idea for an animated series. In this world, crystals have an adverse effect on animals and the world's environment but have the power to grant enhanced abilities. Randall and his family are crystal harvesters in Sahar. The Sahar King decides to wipe out and take the crystals for himself in the hopes of arming his country against their powerful foes.

A few questions I had:
1) How can I make this story more interesting, particularly from the first episode? Someone referred me to the avatar series regarding character dynamics but would it not be possible to establish character dynamics in the first episode?
2) Regarding feedback, some people have said the journey to the city seems boring , how can I introduce these characters better and make the events more interesting?
3) I eventually plan for the main character to chase revenge rather than his mother's wishes - how can I convey this early on as one of my main themes. I also had the idea of Gloria needing to understand that her idea of sacrifice is not going to lead to peace/ which parallels the King's arc of being a people pleaser. Is it okay to have characters have different wants/needs or should they all be related to one theme?
4) Have I introduced too many characters in the pilot outline or is there no limit?
5) Lastly, I've been told that my script is too talky - how can I add more action to my outline?

This is what I had in mind for the first episode:

Act 1
Teaser:  Randall tying up Gloria’s hands and shoving her forward. (Final Image)
Randall, a farmhand.
-Not trusted by his mother to tackle a cheetah guarding a crystal.
- Impatient - jumps too early to attack the cheetah.
