Naruto: Shippuuden, Shingeki no Kyojin Recommendations
"Woah...that's so cool!!!" If you've said this many times in Naruto, you're goona say the same here. Like Naruto, has all you can want in a Shonen anime...action,sadness,coolness,incredibly determined main character just like Naruto, and is similar to Naruto junchuuriki. If you like Naruto, you'll definitely like SnK ;)
Both anime are enthusiastic, artistic and full of action.
If you watched Attack on Titan, then you must definitely watch Naruto Shippuden; you won't regret it!
