I've read up to around issue 45. really really like it.
It does not read well, at least for me, one chunk every month. I've stopped reading it, though I still buy it. I figure I'll sit down with all 100 issues in 5 years. =)
There are just soooo many subplots, little hints dropped in issue 20 that show up in issue 40, tons of characters. It is a very intricate story that is being woven. Lot to keep track of that becomes hard when you haven't read some issues in 5 years. It had got to the point that I had to reread the entire series every 6 months. Didn't bother me, cause its a great series, I just read quite a few books so I don't always have time to reread things 4 or 5 times.
