I haven't yet read the entirety of Miles's previous adventures. But what I have seen, I have liked.
Some of his battles, his humor (CLONE? CLONE! CLONE!!!!!!). His family, his friends, Ganke, his dysfunctional superhero buddies.
I am happy we can continue seeing more of him, developing himself in a new world, with a familiar mentor and with a new team. Alas, like Celgress, I hope some of the above does survive Secret Wars too.
One suggestion for this thread, leo619: more images in the first post, helpful descriptions and an introduction, and links to his series in Comixology and Marvel.com.
(Question: Have those who would like to see a relationship between Kamala and Miles appeared yet?)
