I like MM. He's a visually cool character and he's got cool powers. However, my primary exposure to him was in the JLA title (/the cartoon). That is, I know I like him in the context of a team, and I know that doesn't always translate over to enjoying a book centered on the character. Ex: I like WW in the league, how her character plays off of Superman & Batman, but I have no desire to read her featured title (pre or post new52). (I will acknowledge this is based on assumptions, (and I did enjoy her direct-to-DVD animated movie), but imagining her alone & the supporting cast she brings, I'm not chomping at the bit to read her).
I have a gut-feeling that I might have the same reaction with MM. That it might focus too much (IMO) on the moody/broody aspects of him (since in a team book, it's much more classic-hero-action oriented), and that his supporting cast/stories might not intrigue me as much.
Are any of these "concerns" about a transition from "MM in a team" to "MM alone" warranted?
