Since it is a kids show so I will review from a child’s prospectus. when I was a kid, it was one of my favorite shows and somewhere I was addicted to it.
Because of the gadgets Doraemon gives to nobita it fantasist the children and take them to a dream world. Children loves dream world.
In short, if you are a child, I hope you will love the show and if you are more than 18 than go for some other show like sasural simar ka.
