This movie explains in a very intense way how the whole otaku world is seen (and felt) in japan. It has some major lacks in the storytelling tho. It alternates extremely slow, peaceful events to cruel, terrible and somehow disgusting events which happens so fast that you won't understand anything if you don't watch it at least 3 times. They had an amazing cast, despite their young age. We have a rising Miura Haryma, a powerful Yamada Yu, an always wonderful Narimia Hiroki and great Arakawa Yoshiyoshi (who I feel is still very underestimated). This movie may not suit most of the people taste because of its cruel scenarios but if you want to make a step into understanding the real otaku world, well this is a must-to-see. I also recommend to not eat anything during this movie. It might sound random but... really, snacking won't help.
