This is pretty good in my opinion, probably close to 5-star, but PKD's book is better, and then since the graphic novel is based off the movie images and script, it falls a little short of actually watching Linklater's movie version.
If you like graphic novels and aren't familiar with PKD or the movie, I'd assume this would still be a good choice and enjoyable, and rank as a high quality graphic novel. I know some people are skeptical of the movie presented in rotoscope form, but I recommend it for sure, this graphic novel and the movie are far better than average at adapting science fiction as a whole and PKD's work specifically. The book can be said to be strange, but I don't think its a hard read, so anyone not afraid of words, I recommend reading the book most of all, and not be afraid of the movie, but yes, this graphic novel adaption is pretty good as well.
