As for Morning Glories, I think the stories remain very interesting, but some people complain about the change of focus from the Glories to the Truants or the fact that some questions are still unanswered while new ones arise.
I don't mind that, it's a gradually developing large tapestry with many elements and I'm looking forward to the day when I'll reread this book in its entirety. Nick Spencer talks about it in the MG thread in the Image forum btw, and explains his approach to the story he's telling. ;)
It remains my favourite of the four ongoings I'm still reading, soon to be three after February. :(
