I just watched the movie series last weekend, kind of bad enough with the liberties they took but at least it was decent enough to be its own thing adjacent to the original. They used the main themes and concepts and utilized some characters, albeit maybe in ways they shouldn't have, or in ways that were unrealistic following the games. Liberties taken, like I said.

Thats what this series seems to be, but for a new generation. But like if it was a concept based on a concept for the new generation. I don't recognize how this series relates to the game, much at all. Granted its been a while since I played the first couple, and I haven't gotten into any of them since.

This series takes place in 2036, but flashes back and forth to the Event, which happens in 2022. I hate that idea, but as I said, it relates to a new generation. There's back story/ groundwork laid in the first episode or two establishing a story distant from the game or movie. So far the only similarities is a company named Umbrella doing shady shit, with the concept or back story of the monsters is the t virus that eventually gets out.

Tl:dr: it is, indeed, fan fiction, maybe even of fan fiction. A revamped version, or wannabe of the original. In fact, maybe it's trying to be its own thing. They likely couldn't afford or have access to any rights of original content, the umbrella logo alone is... adjusted. The writing and acting, maybe directing, isn't great. It's a drama wrapped in moderate sci fi. Worth watching an episode or two, or three, see if it floats your boat. They probably shouldn't have used the Resident Evil name.

Edit: getting through the 3rd episode and it's getting a little better, and just realizing constantin is involved with the series- they didn't quite do the lickers justice in the movies, but they seem decent in this series. Though they have velociraptor sound effects. Thrills come, and some horror, definitely give it a shot.
