Well I meant more specifically what they were unhappy with, though I think you and I have guessed what that is. But again after reading the full article, its clear they want someone to help him with this, but after reading THRs article to me it seems they are doing all this for the better and Edwards is still involved, though, seems Gilroy is taking the lead on it.
But again I dont think all is lost. Godzillas problem was flat characters, everything else was good, so Im thinking/hoping thats what they are working on to make us love the characters like we did with the last film.
