I don't expect it to be that great, but I'll watch it and it'll probably be entertaining enough.
I'm assuming the reason they chose to film this in South Africa was because they needed scenes involving the discovery of the Progenitor Virus (which in the games, it's discovered in South Africa and that's where things really get going). Going to be weird to see them try to fake Maryland in South Africa as well, though, but I guess that'd be easier than the other way around (faking Africa within Maryland).
This actually fits entirely with something that was rumored years ago, I can't find it but I really do remember a rumor from several years ago about a Resident Evil TV series that got greenlit about the creation of the T-Virus, the first major outbreak, and three powerful factions trying to cover it up, and the series going to be more about conspiracies and the horror of secrets and a town going to Hell. I can't find this anymore, but I swear this plot detail sounds almost exactly like the rumor from years back.
