Starlin is easily the best when it comes to writing cosmic Marvel stuff(and his Batman isn't anything to scoff at either lol). Anything he writes I pretty much pick up...at least at some point.
I def didn't dislike Thanos Imperative, but there was something about it that didn't do it for me. Either way, to me, it's required reading. And I believe this next issue of current GotG run will finally answer some questions.
And I def believe we aren't getting those row in MCU. Unless marvel buys back FF, I don't see fox selling rights to those two characters alone. Hopefully I'm wrong lol.
