Montini's achilles heel was his own long tenure in the bureaucracy that fought to water down or undermine the work of Vatican II.  Though he fostered ample debate during the Council, he yielded to the bureaucracy at key moments to close off that debate.  His insistence on as much unanimity as possible on final votes led to juxtapositions of the status quo beside reforming insights (see chapters 2 and 3 of Lumen Gentium).  His appointment of special commissions to implement council decrees led to greater participation in implementing the reform, but when the commissions adjourned the church was left with an unreformed bureaucracy that resisted the reforms.  His failure to trust the bishops and the local churches to receive and carry out the enhanced vision from the Council led to uneven development and the bow to restorationism that followed his death.  Montini's papacy with its mixed result provides one more reason to return to a centuries-long reluctance to canonize a pope.
