I was disappointed in it because of the location they shot from. It's taken from János hegy. Although this is the highest point in Budapest, it is so far from the city itself that there isn't much to see.
There is some waffle on the page about why they chose that point. They say it is the highest point and that the observation platform there will have its 100th anniversary in September. But then there is mention of the support and cooperation that they had from the district council for that district of Budapest.
So presumably the authorities responsible for the other more reasonable vantage points were less cooperative.
