I disagree regarding part of no adult actors & actresses can outshine them. The strong impression of child actors outshining adult actors is not because of acting. It's because child actors introduce us to the story, and adult further carry it. If I've to give an analogy it's like child actors started singing the intro and adult actors were left with chorus.
It's a pity, could have been great, not saying it wasn't good. I loved the beginning episodes but as the story…
On the contrary I think that he was pretty decisive. SFL comes back in 3-4 episode. Then, ML and SFL reconcile in episode 7 (I think). ML and FL get together in episode 10.
I apologise if my comment hurt your sentiment.
