If you read many of the threads about the current Avengers title, a lot of fans have an issue with writer Jason Aaron.
My issue is that he trys to go too big with all of his stories, some I have liked but most I have been left scratching my head thinking wtf ?.
Aaron has most of the best tools from the Avengers tool shed, e.g. Captain America, Thor, Iron Man, Black Panther, Captain Marvel and She Hulk, he has added Ghost Rider (Robbie Reyes), Doctor Strange, Blade and just recently Echo the new host of the Phoenix Force. I believe a major part of what is missing from this title is his character growth and their daily interactions with each other.
Big isn't always better and it is the small things that are missing that is distancing the fans imo.
