Pakistan's problem is emblematic in many of the posts in this thread. At a fundamental level, we have been searching for a 'great leader' in the singular since the premature passing of Jinnah.
What Pakistan, like any modern nation state, needs is a functioning opposition or alternative that isn't corrupt. A lack of corruption does not in of itself create an efficient, good government: it just means that the very top level won't be siphoning money off the top. See for example many governments in the West - anti-corrupt but inefficient, stagnating, running out of steam in policy terms. What happens in this country is that there is an opposition and an established tradition of elections, whereby if Party A is not seen as capable, Party B is usually elected in. The competition between Party A/B usually serves as an incentive for good performance too, whereas I think in the case of PTI, and certainly many people's support for them, anti-corruption was erroneously thought to be enough.
We have an 'all eggs in one basket' problem, to which the only viable alternative that I can see for the establishment is to return to some form of modified status quo with Shehbaz Sharif as PM (anyone but Nawaz). That, obviously, is not ideal - it cements dynastic politics in this country.
I am a big supporter of IK in the broad Pakistani sense many of us will mean - he is anti-corruption, has good ideals and recognizes the importance of sorting out Pakistan structurally (tax base, fixing our education system, becoming export driven, establishing rule of law, etc). But his present government is also inefficient and he doesn't seem to have a workable way to deliver his big ideas into policy (this is one area where in the West the democratic competition will force parties how they will actually do their policies). Of course, some will mitigate this by saying that the team around him, or even the culture, isn't there. That is a fair point - this lack of concrete policy delivery in Pakistan is a systemic issue and is why the big parties have only ever focused on very simple (in policy terms) infrastructure projects or at best, relatively simple to implement benefit programmes (Benazir Income Support, Insaaf health card). This is not only an issue with Pakistan's political class, but also its bureaucratic class: our civil service is inept and I think anything that is truly more challenging in policy terms is beyond them. I mean, the only thing it can do is tender out construction projects and run very simple benefit programmes where all is needed to be done is an application processed and a notification for X monies to be deposited in Y's person's bank account on Z interval.
