Little Nemo is one of the unusual cartoons. The reason is a combination of Japanese animation and American script and English borrowed voices.
Originally, Nemo was actually a comic created in 1905 (yes, it's so old) by author Winsor McCay and followed the unusual adventures of Nemo in his dreams where he would usually wake up in the last picture of the comic. He used his son Robert for the template for Nemo and drew a comic that came out, intermittently, for over 20 years.
The animated version went through problems, the script changed like the screenwriters and in the end we got the aforementioned combination where we have a Japanese director, an American screenwriter and English actors. Even the great Miyazaki participated in the beginnings as early as the first half of the 80s, but he leaves because of disagreements and himself later declares that this work was one of the worst experiences of his life. Side note: the script eventually went to Chris Columbus who is best known as the director of the first two films Home Alone and the first two films of Harry Potter.
The film was originally released in cinemas in Japan in 1989, and after 3 years in America. He received mixed reviews and did not earn close to what was expected, however, later on by going on VHS he gained a lot of popularity and today enjoys a cult status with a certain audience.
In the film, we also follow the boy Nemo who goes to Slumberland in a dream, meets various characters such as Professor Genius, King Morpheus, Princess Camille, clown Flip, and is always accompanied by Icarus, the flying squirrel. All characters have appropriate names. I can say that this is by no means an easy cartoon. Nemo reflects reality in his dreams (which is logical), he often wakes up and we can't always be sure what a dream is and what isn't, at least not while watching. We have a situation where something unusual happens, so we know that it is a dream, but then Nemo wakes up, but strange things start happening again, which means that the second dream has started, that is, that Nemo dreams while dreaming. I remind you that this is a cartoon for kids and that Inception comes out a full twenty years after. There is one more thing I have to mention. When the nightmare starts and we meet the Nightmare King (I said the names are appropriate) quite intense, scary and dark scenes appear. Whoever watched knows what I'm talking about. Since I was 5-6 years old when I first watched those scenes, they were the scariest thing in my life, we have nightmares myself (haha ingenious when you think about it) because of the King of Nightmares. When I looked at him again as an adult, I can absolutely understand why this was scary for me (and I believe many other children) to watch. A nightmare is a de facto nightmare. I have to commend this film for its courage and determination to insert a little more serious themes into the children's cartoon, making it a little more complicated than the average cartoon. That is why I think that it is unique and that it can offer something to adults who watch it together with children. They will not be bored or monotonous for sure.
