Exactly. The reason the "plot" development's been slow as of late, is precisely because the story's been focusing on *character* development. The best stories have to have parts that are plot-driven, and at other times, character-driven. A good writer knows when to switch between the two.
Contrary to other commenters, I believe there is significant development in the story (albeit at a pacing many may find slow). Right now we are in the thick of Seth's redemption arc. Seth was initially fighting against the souls of the dead (mass slaughter) but now he has come to terms with them and was able to channel them during his fight. I feel that this is crucial part in his character development. You can even see the change in his demeanour when you compare earlier arcs to the current one. It only really feels slow because we get to see just glimpses every week and that there are many characters to cover (e.g., hopping between horus, isis, anubis).
