Some information on the naruto series.
It is divided into 2 parts , naruto (220 ep) and naruto shippuden (500 ep). The total number of episodes , as you can see are 720 . But 40% of the episodes are filler . A filler episode is not related to the story and can be skipped , it is optional to watch them . The list of fillers can be easily found on the internet . I personally did watch all the fillers , but it is up to you to watch them or not . The other 60% episodes are canon episodes i.e they are a part of the story and hence can not and should not be skipped . The canon episodes are based on the manga . The manga is the origin of the anime , nowadays there are anime without manga but naruto has it’s manga . It was written by masashi kishimoto and contains 72 volumes (books). There is no filler content in the manga . The manga can also be easily found online to read just as the anime .
Other than that there are 10 naruto movies and a few ova . The first 9 movies are filler while the last one is canon . Ova are short 5-10 minutes extras which are also filler but fun to watch.
Lastly there is boruto after naruto shippuden , it isn’t that fun to watch in my opinion . The newer episodes are starting to get interesting but not the starting one’s of boruto .
Lastly if you have any questions regarding naruto do not google them as you will be subjected to a lot of spoilers . Naruto is a big anime and all the questions will be cleared in the anime itself as you progress .
Naruto was the first anime that I watched and I rate it a solid 9.5/10 . It was really fun to watch , I hope it is as fun for you . Enjoy your naruto journey!
