Corbyn proposed to make the Labour party back into a movement, controlled by its members and not by its members of parliament. He proposed to reject the Blairite 'big tent.' You can agree or disagree, but he didn't apply to lead a big tent party, he applied to change the very nature of that party. (Think Svend Robinson and the New Politics Initiative - a leadership campaign based on changing the NDP into a vehicle for social movements, not a big tent.) The membership by a large margin accepted his proposal. It's rich to now turn around and fault him for doing what he promised to do. It's rich to take a leader who has returned the party's electoral fortune and delivered the bulk of its vote to remain, and demand he step down. It's rich to criticize his critical support for the EU as 'weak campaigning' when it was so much more effective than the train wreck David Cameron delivered.
