I need to start off by saying I understand the appeal of The Mandela Catalogue. However, it's just not for me; I simply cannot be bothered to continue watching the series. I don't think the execution is bad or anything. Maybe the only issue I have with the writing is that everything is a little hard to follow, though that seems to be a trait of all found-footage media. However, I've enjoyed other found-footage films before, so I don't know why The Mandela Catalogue seems to be the outlier. Maybe because it's a web series? In any case, I suspect my unflattering rating is all a result of my own interests and dislikes.
I did mildly enjoy the videos I watched, though. I might not finish the rest of the series but I also don't feel like I wasted my time, so 6 stars for that. In general, this was a slightly above mediocre experience for me.
