Your mileage may vary
I found this in on The Christian Left's Facebook page. I'm a fan of the American political system: come on, you have to love a system built on the fundamental assumption that politicians are greedy cheating bastards who need to be kept in check. And one which actually answers the question Quis custodiet ipsos custodes? But it's not for every country (the UK has many flaws but they don't result from its parliamentary system) and given the USA's habit of exporting dictatorships rather than democracy in any event (Iran, Chile, Nicaragua....) one could hardly blame other countries for scepticism.
