You could say "But it continues those plot points in the manga," to which I'd say, "It's the purpose of the anime to properly adapt the manga, so that the story makes sense to someone who only watches the anime." A good example of this is Zodd, he shows up in the anime for one scene and is built up as a huge villain, but he NEVER returns, he only serves as a tool to foreshadow the actual future villains and they still come out of nowhere.
Furthermore, I could barely even bring myself to watch episode one after watching episode twenty-five (episode one happens after episode twenty-five canonically, but you can watch it before or after). The constant themes of rape and gore are just too prevalent throughout the series, and often unnecessary for the forward motion of the plot. One of the only things I enjoyed consistently throughout the series was the soundtrack.
