Sentry, as a character, has been horrible mishandled by the writers. It's almost like they don't really know what to do with him, but they still want to use him.
I'm of the belief that he could be a great character. Perhaps in an "Alan Moore on Supreme" kind of way. But there's no chance of this happening while Dark Reign is going on. First Norman and the Void need to be dealt with, only then can the healing start.
Is it strange that I kind of like Ares? I look at the character, and I think "I should hate this guy." But I don't.
