In some part I think that maybe I'm getting older, and the world around is more violent, and the stories are probably good, but they don't hold my attention the way they used to.
But really - I miss the days where I was completely ENGROSSED in a monthly. The trips to the comic shops weren't "when I had time" - it was to the DAY to see what happened next.
I feel a large part of it is due to the constant shift in writers - each new one comes along to "shake things up" and make his mark - and the characterization and development fall through the cracks.
