I had no problem understanding the dialog, but if you have issues understanding African accents, then maybe you should skip it. I remember when I was in Africa, we were on a shuttle with a couple of other people, and although they spoke English, and the driver spoke English, they couldn't understand anything he was saying. It was in the strange position of translating English to English. I can understand where you're coming from. I have similar problems in the Deep South. One time in Alabama, I blew out a tire and we stopped in a repair shop. I couldn't understand what the guy was saying and my wife had to translate. Also, I sometimes have to turn on closed captioning when I'm watching a TV show from the BBC.
