Mm, I dunno; to me, Cell represents a culmination of everything Goku's gone up against, and it was nice to have it as a sequel to the Red Ribbon Army arc.I agree. While I don't know what the original intention was, it at least felt like Radditz -> Saiyans -> Namek -> Freiza was a cohesive story that incrementally raises the stakes and has a satisfying conclusion.
While the Goku/Gohan bit is a nice, the Cell saga feels like a DLC you play after the fact that actively shits on the story and themes set up in the previous arcs.
