You may be interested in Anime And Philosophy by Josef Steiff (Editor), Tristan D. Tamplin (Editor) from Open Court Publishing series Popular Culture And Philosophy. All the books from the series I've read are quite enjoyable. They also have Manga And Philosophy, if you are interested in that.
Funny enough, I recently realized that there is another series, The Blackwell Philosophy And Popular Culture - before I thought it was all one series, but obviously there is enough interest in the market.
Both series are easy to read. For comparison, The Philosophy of the Beats is noticeably more dense. Not sure if this is helpful.
Note: I do not have a philosophical education, but the contributors seem to be credentialed.
