Tastes in artstyle and ambiance are something that is different for each individual. I’ll write this anime from my perspective, but if the screenshots in the Anime-Planet entry were already raising doubts at your end, don’t bother.
The Diary of Tortov Roddle is a series of very short stories of 2-3 minutes each. They show the peculiarities Tortov comes across as he travels through his fantasy world, riding around on his Dali-like pig.
While the short stories are interesting by themselves, what made this little show so enjoyable was the art. Made by the same creators as the Oscar-winning La Maison en Petits Cubes, Tortov is completely hand-drawn and makes good use of surrealism to create its world and story.
There’s not a huge audience out there who are into this kind of style. To those who are however, The Diary of Tortov Roddle is a must watch. It’s very short and jumps up and down a bit in quality towards the ending, but frankly, I didn’t care. Enjoyed it from start to finish.
