I hope Luke's father sticks around for a long, long time. People from that era lend a special voice and message and tenor that needs to be heard by the present generation. And while I realize that Blue Marvel and others are long-lived, nothing bridges the gap like the perspective of a "normal" human.
On a less positive note, I'm ready to put the Original Sins plot in the rear view mirror. I'm ready to see this team take on some of the more established powers. I wonder if a Mighty Avengers version of the Masters of Evil is in the works?
