Last week, I read a comic book called : "Doraemon - the cat robot from the future". As you know, Doraemon is the main character in that story. One of my favorite movies is Doraemon which I have watched since I was a child. The movie tells the story of a futuristic Doraemon cat with a lot of smart gadgets to help a somewhat clumsy and stupid student, Nobita. Doraemon was at Nobita’s house to help Nobita study as well as help him solve problems arising from school and his friends including big and fierce friend Takeshi Gouda, the sneaky friend Suneo Honekawa and the beautiful Shizuka Minamoto. All the characters together create cool, engaging, and humorous anime episodes. I’ve been watching Doraemon movies since I was in third grade. This is a movie that I’ve watched quite a lot but not bored. Thanks to the Doraemon movie, I have had some new friends.
