Some anime-specific websites like Crunchyroll or Funimation could have the English dubbed version of Ghost Stories anime. But make sure to check their subscription requirements and regional availability.
Overall, the English dub is okay. The translation is understandable, and the voice actors do a passable job, but it might not capture all the nuances of the original.
I think it's worth watching. The voice acting and the way the story is presented in the dub make it an interesting watch. However, it's not a perfect adaptation and has its flaws.
