This series was a solid, albeit unnecessary revamp of the Grudge origin story. It's nothing we haven't seen before in terms of story, but its execution feels more authentic here, and gruesome enough to easily warrant its TV-MA rating. I'm glad they decided to keep this origin series within its original Japanese roots instead of Americanizing it once again, as we've all seen how those have turned out... Overall a solid series, though it would've probably worked better as a 2 hour Japanese film instead.
