This is precisely it, it's very character driven, but the older generation characters are so much more interesting than the younger generation! So to make it almost exclusively about the younger generation made it so much less interesting.

"Who are the good guys?" is the question I was asking when it was interesting. "Why do I care who this girl's father is?" is what I was asking when I wanted to know how much longer the film was going to last. Again, "Who are the good guys?" is very set around the older generation, it's generally tightly linked to the Comedian, and it was interesting.
