I know plenty of south african people, this just sounded like a bad parody and it seemed to get worse every minute. In general all the accents sounded really off, like they were trying to go for some kind of futuristic lingo like in after earth but equally failed in the execution.

English is not may language but I usually watch movies in english without subtitles, some accents give me a hard time scottish, welsh, southern US but if this a south african accent, then I guess it's the one I'm having the biggest problem with! It's the first time that I hear a south african accent and to me it sounded "fake", totally made up , but then again, as I said, I am not a native english speaker. No offence meant to anyone.
Someone mentioned "Fury" that's one I should have watched with subtitles, I found it very hard to understand.
"Please, if you are trying to convert me, this isn't a good time"

Well, the actor IS South African. And he had a South African accent. Is that strange?
