The stupid production company have dubbed the interviewees who speak good English with American actors speaking English. Apart from the fact that it's insulting to the local population, it is quite annoying.
They dont reduce the volume of the person speaking, so it sounds like there is an echo, which is quite off putting.
They also often dub everything, so if the interviewee meets friends who laugh, they include laughter. Also annoying is that they include subtitles as well.
