Just a guess, but I think Filoni is creating a family environment in just these first episodes. There’s some mild drama and action here and there, but it’s mostly the calm before the storm. The Colossus is a tight community and we are about to see people tested, bonds broken and new one formed, and all sorts of challenges when entire planets, multiple planets, are destroyed.
Any future episodes with action and drama are only going to be benefited by the character building in these early episodes.
