Yes, Watership Down is amazing.
And I had a phenomenon, I probably never had before. After finishing the book, I liked the series even more, because I was realizing all the small details, the creators of the series put in. I mean, the series is very different from the book, but the creators nearly always keep the spirit of the book (maybe only despite from the end of the series).
