One of Marvel Comics' primary problems is that they got rid of or fundamentally changed for the worse the majority of their beloved old guard within the period of two or three years. Fantastic Four? Missing in action. Captain America? Literal Nazi. Hulk? Dead, killed by Hawkeye. Tony Stark? Dead. Wolverine? Dead. Thor? Lost his arm and hammer. That honked off the majority of the few loyal "Marvel zombies" that remained. So sales plummeted. The May 2017 sales figures came out recently, and they're terrible.
