Ugh, not this again.
Bendis is a great writer whose Avengers run enjoyed critical and commercial success and got thousands of people interested in the Avengers. He has his weaknesses (like any writer) and did experience creative burn out towards the end but threads like this just reek of fan over reaction to their favorite character not getting the spotlight or being written differently. Not to mention fans who refuse to accept new ideas or characters in the Avengers.
No amount of modern revisionism by the vocal internet minority can change the good work Bendis has done.
