A great piece by Shigeaki Saegusa.
Starting in 2009, Toei's refurbished, "refreshed" version of Dragon Ball Z began to air on FujiTV. It recieved high ratings throughout, but was cancelled after 98 episodes (97 aired, 1 DVD/Blu-Ray exclusive). The purpose behind this creation, Dragon Ball Kai, was, besides celebrating the 20th anniversary of DBZ, was to provide a filler-free version of the show, staying closer to the original manga by Akira Toriyama. It was even touted as the "Toriyama Akira Original Cut Version". There would, as a consequence, be fewer episodes.
Episode 98, "Peace for the Future! Goku's Soul Lasts Forever"
Episode 97, "Farewell with a Smile! Heading for New Days..."
Personally, find the Blu-Ray footage too dark, but otherwise the remaster looks surprisingly solid for a Funimation release, even if I prefer the Dragon Boxes.
Episode 96, "Combine Our Power! The Mightiest, Final Kamehameha"
Episode 95, "Bye Bye, Everyone! This is the Only Way to Save Earth"
Episode 94, "The Perfect Form Breaks Down! The Super Iron Fists of Rage Explode"
