As Nobita hears a pirate story, he dreams of going hunting for treasure himself and using Doraemon's gadgets he surprisingly discovers some undiscovered treasure. The treasure was located on a newly formed island of rock outside of Japan but as they make their way there, they are attacked by a group of time travelling pirates and Shizuka is kidnapped. Now they must rescue her from these mysterious assailants. A new original movie for 2018 even though the pattern's been remake of an old movie followed by an original. Interestingly enough, Genki Kawamura was responsible for the screenplay - he was one of the producers for YourName and also The Boy and The Beast.

As usual the art is good and this was actually quite a good action comedy. Shizuka gets a lot more screen time than she usually does. They added in a bunch of little riddles in for fun too and movie doesn't forget to empthasise on protecting Earth and its environment as its been with previous movies.

Worth a watch for Doraemon fans.
