This is just my opinion; Losing Brubaker, Fraction, Remender, Ellis, Hickman, Hitch, Millar, and Gillen did not help them. Aaron and Lemire are all that remains. Aaron is doing Star Wars, Doctor Strange, Unworthy Thor and Mighty Thor. (while still doing Southern Bastards and Goddamned). Lemire is doing Thanos, OML, & Moonknight. They are all pretty solid books. After that its a pretty big drop.
I'm curious to see where Marvel will go and how they will fix this mess that they got themselves in. Perhaps have the Fantastic Four see all the damage that they have done and try to fix it while bringing them back. 2 birds with one stone.
