I personally thought that this show was amazing! I liked the plot and characters a lot. It was a unique anime, which I liked. It wasn't like anything I have watched before. The characters, in my opinion, were complex, especially Rachel. Without spoiling too much I can say that the ending was very good in my opinion. I feel it was the perfect ending for the series. I don't know if there will be another season but I feel like there doesn't have to be. I know the score for the show is pretty low but I would recommend watching it. Not the best anime ofall time but still worth watching.
