The letter for the King is an epic fantasy focusing on teens.
The first two episodes were too long and rather slow, but then it got interesting throughout the rest.
The first twist on episode 5 least surprising, but the second twist right near the end...it turned out it was never the boy but the girl who had the power! I was mindblown by that surprising twist!
Every episode was worth the watch.
The question is, will there be a second series?
