Look there are a lot of things that are wrong with PADI as well as most recreational agencies (and it mainly has to do with the way they push the creation of bad and ill prepared instructors). But dividing the course into OW/AOW/Rescue is NOT one of them. I believe this is truly one of the great advantages. It allows people (divers) to really take the information bit by bit, instead of being forced into becoming a fanatic for diving from day zero (keeping the numbers of divers very low). This allows people to commit slowly into a hobby they might or might not like. It allows instructors to give quicker, less involving courses, which in turn allows them to via this same modularization, find different ways to teach classes and to assemble diving groups.
The flaw in the system is not being modular, it´s the bad instructors, as it has always been. Agencies DO have a very big chunk of responsibility for churning out so many bad instructors, granted. But it´s not the system, it´s the players at fault.
