I would agree in so far that some of the new councilors seemed to be either naive or slow learners. A number of them had little or no experience in business or in running a larger organization so that may be part of the reason.
I have watched councils in the past and yes there does seem to some time, around a year or two, for new people to get up to speed. However, in so far as I can tell, this group hasn't really yet.
Bureaucracy can excel at being unable to distinguish the trivial from the important and by proposing overly complex or cumbersome solutions, so this is also why Council has to show more leadership and clearer direction.
