As a Zimbabwean I cringe every time they speak in Shona, they didn't do much research or take time to learn the language. That accent is like a 2 year old learning to speak.... yes that's how bad it is. they should improve their Shona dialogue delivery to make it sound more original.
however on the positive I enjoyed the series Giancarlo is a great actor and always delivers. I feel his grief and how much he is trying o be a better person. the story line needs more work done but overall its a good watch quite suspenseful
