If you have never seen Jojo's before, start with the newer anime. This is only worth watching if you have already watched/read Jojo's part 3. A lot of parts of this are pretty laughably bad, due to weird changes in the story to save time. However, the final fight of this is REALLY well done and is honestly better than the newer anime. The retro aesthetic looks great with Jojo and is way better in the final fight, but the animation also seems really slow the rest of the time. I would definitely recommend watching the final fight, but you can skip out on therest unless you are an extreme Jojo fan.
