Watching HELLO WORLDhttps://anilist.co/anime/106240/HELLOWORLD/ was really something. It simply left me astonished mind boggled and it left me with something I could just think about for hours on end. This review will have heavy spoilers delving very deep into the story and its potential meanings. Although I wasnt expecting much with its measly 73 on anilist I still had high hopes in finding something that would leave an impact. Hours after watching I still dont really know my stance on this movie which isnt really a good or bad thing. This movie was really just full of concepts that youd need to get your head around at every corner. Even up until the very end I just couldnt stop thinking about what this movie really wanted to convey. The Story Im actually just going to skip most of this entire section because if youre reading this very spoiler heavy review I assume that youve already watched the movie. If youre looking for a nonspoiler review to see if youd like to watch the movie then Id recommend Prowlers reviewhttps://anilist.co/review/23665. Well call the first setting where the younger Naomi lives Layer 2. Well just call the younger Naomi by his name and the older Naomi by Sensei. Correspondingly well call Senseis world Layer 1 and well call the world above that Layer 0. There is only really ever 1 Ruri present throughout the entire story until the final scene. After Sensei uses Naomi to save Ruri and bring her back to Layer 1 he initiates a recovery in the system which deletes and restarts the data killing Naomi. However Naomi lives instead of being deleted being saved by the crow Layer 0 Ruri which leads him into Layer 1. Sensei goes to Ruri but Ruri knows that it isnt the same Naomi that she was just with and the homeostatic system appears and attempts to remove the discrepancy in the data of Layer 1. Naomi saves Ruri yet again in Layer 1 and the crow leads them to an entrance to a new world. In the process of going to the new world the homeostatic system attempts to eliminate one of the two Naomis as there shouldnt be two. Sensei gives up his life for Naomi to meet Ruri in the new world. Meanwhile Sensei wakes up from a coma in Layer 0 where Ruri has been supposedly trying to recover him just as Sensei was trying to recover Ruri. Theories The first thing I want to talk about is the fact that the crow is Ruris avatar from Layer 0 unbeknownst to Sensei. This can be confirmed through the similarity in their voices when Sensei wakes up from his coma in the final scene. After contemplating this story for a while me and my friend came to the conclusion that Ruri initiated the entire storyline all the way at the start by helping Sensei save Ruri in Layer 2. This was to contribute to her end goal of having Sensei sacrifice himself and then supposedly take him and implant him into his body in Layer 0. Thus syncing his mind and body which was the requirement for reviving Ruri. Another theory that was explored but is extremely far fetched is the fact that the pretty girl from Layer 2 was the crow which is why she was following Naomi and Ruri around so much. I personally dont believe this theory to be true. I dont believe that both Naomis were the same as Sensei went through some character development in Layer 1 where he realised he was wrong and decided to help Naomi save Ruri. If they were the same Naomi wouldve seen how everything would play out and in the future as sensei help Naomi from the beginning. I could see how this would work with Ruri if Naomi was out of the picture though. Whether Layer 0 is still part of the data world is unknown and widely theorized. Theres no evidence to indicate that it is or isnt so that will just stay as it is. Review Finally onto the actual review. The story and plot was amazingly complex but there were ways that they could have made it more cohesive. It felt as though the end of the movie was near when I was only halfway in and then the ending seemed so far away once I got close to the finish. I would give the story a 9/10 The animation really caught me off guard at the start. It really seemed like it was just a really long anime game cutscene but then you get used to it a little. Im not really a fan of heavy cgi use in anime. 7/10 There isnt much to say about the sound music and voice acting. They all seemed all right and didnt have a huge effect on the story or tone. 8/10 Overall HELLO WORLD is a movie with an overly complex storyline and a fastpaced structure. Its a nice watch and can leave you somewhat satisfied after you figure out all the little story elements. 8.5/10
