The sequel to Naruto's first part is bigger, better, and most definitely worth your time. This is an anime every anime fan should see, a timeless masterpiece.
There's a reason Naruto is part of The Big 3 Shounens. Like all anime and manga it has its shortcomings, so I'll talk about what's good and what's not. Overall however, this is beyond phenomenal.
First off, if you want the best experience watching Naruto: skip all the fillers. And I mean all of them. I'll talk about that later.
I don't even know where to start with why I love this masterpiece. As if the 'original' Naruto series wasn't already fantastic Shippuden cranks things up to 100; mostly for the better. The 220 episodes of Naruto hyped up the Akatsuki, and they sure as hell delivered
Characters: I've never seen more 10/10 characters in one anime. Shippuden introduces almost double the amount of important characters and they all are beyond amazing. It just gets better as you watch.
Fights: 10/10. Easy. Mob Psycho, Chainsaw Man, and Jojo tier-fights. Apart from some of them being a bit drawn out these are some of the most logical, entertaining, consistent, and emotional fights.
Plot & Filler: The canon plot is slightly drawn out, especially the last arc of Shippuden, but it nonetheless is a 10/10. The characters, fights, plot twists, and everything in between are so addictive and fun to watch. Now filler. 'Older' animes used to add a bunch of filler, god knows why, and naruto is certainly one of them. Over 200 episode in Shippuden are filler. Two. Hundred. And they are horrible, just like part 1 of Naruto. Don't do what I did and sit through every one of them, it's not worth it. Skip all of it, genuinely only 8 or so episodes out of the 300 naruto filler episodes spanning this and part one are worth it: The Kakashi Mask episode (part 1) and Kakashi's Anbu arc.
Overall: 9.8/10
There's a reason Naruto is and will forever be one of the most popular and highly loved anime of all time. A must watch for anyone who finished part 1, and if you haven't seen part 1 you should. It's incredible. This is an explosion of art, simple as that.
