No, skip them. For both series. The problem with Shippuden later on becomes that they start to intermesh the canon story and the filler in the same episode, so it becomes nearly impossible to actually skip the filler unless you have time stamps to use as a guide for fast-forwarding through the non-canon parts.
If you want to give some of the filler a try AFTER you finish watching the series, then there are some that I did not find to be completely terrible. But very, very little.
And not worth slogging through it on a first watch.
9/10 times the filler is not worth watching, drags things out to insane and unnecessary lengths, all because the studio is so busy sucking up money that they don’t care anymore about adapting the freaking manga. They didn’t even do the final chapter of the manga as part of Shippuden. Instead, AFTER the part where the series should have ended, they gave us an entire season of filler and then stuck the final chapter in as a SEPARATE MOVIE. One chapter. Turned into a movie. Just so that you’d have to buy it to see the end of the series.
That’s how bad this studio’s handling has been.
They were scraping the bottom of the barrel so hard that they were reusing filler from Naruto in Naruto Shippuden. Ninja ostriches. Stupidest idea ever. Oh, and ninja robots. That just exist. For some reason.
And at the most climactic and exciting parts, they interrupted the main story to pull us away into multiple story arcs composed entirely of filler. So much so that people had a hard time remembering what was even happening in the real story.
Nearly two years of filler, when the manga was already done. And then they STILL inserted filler episodes and filler story arcs and filler seasons after they were supposedly doing the actual canon story again.
I can’t care about the filler anymore.
Because none of it actually happened. It’s all meaningless, made-up, time-wasting, there to pad out the series for more money.
I’d recommend just reading the manga.
Once you’ve read the manga, if you still want to watch Shippuden, you’ll have a better idea of what belongs there, what doesn’t, and what to skip.Get eBook Info Here
