I’m unsure about how faithfully this series portrays actual events or individuals, so I won't be evaluating it as a historical drama. Nevertheless, the production values are undeniable; every aspect—the visuals, direction, acting, and general presentation—is exceptionally well done. It is also quite dark and disturbing, meaning viewers who are easily upset should probably avoid it. The performance of the actor portraying Ed Gein is particularly impressive!
