V Jump magazine released the large and glossy "Dragon Ball 30th Anniversary Super History Book" to celebrate the series' 30th anniversary on Thursday, featuring full-color pages, art and behind-the-scenes information, according to Otaku USA. However, the most interesting part of the book is an interview with "Dragon Ball" creator Akira Toriyama himself that has sparked more than a bit of controversy.

"Inside me, 'Dragon Ball' became a thing of the past, but later I got upset at the live-action film, revised the script for the anime film, and complained about the quality of the TV anime," Toriyama said in the interview, according to Anime News Network. "I guess at some point it became a work that I like so much that I can't leave it alone."

"Dragon Ball Super," currently in production, is certainly receiving its share of criticism from fans based on the production quality, according to Crunchyroll, so it seems likely that Toriyama is referring to "Super" in his comments, although he could be referring to "GT" (Grand Tour)," which has received a fair amount of disapproval from fans as well. As for the live-action adaptation, "Dragon Ball: Evolution," if I, you, or anyone else were him, we'd be unhappy with how it was handled.

It is unclear which anime film Toriyama is referring to, as he was directly involved in both "Battle of Gods" and "Resurrection 'F'," which were released in 2013 and 2015, respectively. Of all the Japanese films shown in theaters, "Battle of Gods" was the first film to be screened at IMAX Digital Theaters, and "Resurrection 'F'" was the first to be screened in IMAX 3-D, as well as the first to be screened at 4DX theaters, according to Crunchyroll.
