Probably the best work of Rumiko Takahashi, one of Japan's best-known and wealthiest female manga artists. In InuYasha, Rumiko reworked characters from her previous series Ranma 1/2, and polished ideas she had explored in previous works.

This is one of the best animes of all time (although probably better if you watch it during your teens than as an adult) and one of the few with a proper ending for the series. And despite having a lot of fillers, some of them are good quality and aimed to expand character development.

About The Dubs

The Latin American Dub is excellent, and find it the best version of all in case you know Spanish. The English Dub is also very good, but they change the voice actors for the Final Arc and some of the new voices are not as good as the first season. I prefer dubs over subs for a show like this, but obviously, the Sub is also an excellent option if you prefer reading or know Japanese (yes, I have rewatched the series in all these languages over the years, lol).

I'll have to note, among the differences between the dubs, in the Latin & Sub, the character of Kikyo comes off as a tragic heroine who is very sympathetic. While in the English Dub, she comes off more as an evil B**ch. Perhaps due to the subtle differences in tone between the voice actors as they deliver the same lines. In this sense, the Latin Dub is closer to the original Sub.

================================================

INUYASHA WATCHING GUIDE

• Watch Episodes 1-54
• Optional InuYasha The Movie 1: Affections Touching Across Time
  • This is a good movie, but not essential to the main story.
  • The same is true for all movies, they are just filler side stories. They have no relevance to the main plot.
  • They also create some inconsistencies, so they don't fit perfectly in the timeline and in order to avoid spoilers is best you watch them after the recommended episodes. Having said that, you can wait to watch them after you finish the whole series.
• Watch Episodes 55-58
• Optional Filler Episodes 59 
  • This episode expands on Sango's character development.
• Watch Episodes 60-62
• Watch Filler Episodes 63-64 
  • This is the continuation and conclusion of the previous story.
  • I also find the comedic relief hilarious!
• Skip Filler Episodes 65 
  • This is just average comedic relief. It's about Myoga the flea.
• Watch Episodes 66-67
• Optional Filler Episode 68 - Shippo Gets an Angry Challenge
  • This is a classic episode of the series and a fan favorite, however, is all comedic relief and very childish. You can watch the intro to have an idea of what is about.
• Watch Episodes 69-71
• Optional Filler Episode 72 - Totosai's Rigid Training 
  • Cute story but average.
• Watch Episodes 73-74
• Skip Filler Episodes 75-77 - The Panther Devas Arc 
  • This is just an average mini-arc and the character development between Sesshomaru & Inuyasha gets ignored in future episodes, so it only serves to confuse their relationship.
• Watch Filler Episode 78 - Only You, Sango 
  • A fun episode about the relationship between Miroku & Sango.
• Optional Filler Episode 79 - Jaken's Plan to Steal Tetsusaiga 
  • It is average comedic relief, what's important is at the end of the episode, so skip toward the end if you find it boring. You'll find out what happened in the next episode anyway.
• Watch Episodes 80-84
• Optional Episodes 85-86
  • Despite being canon episodes, they are just an average story of another exorcism with some comedy. They are not bad, just average.
  • Is not really essential to the main plot.
• Watch Episode 87 - Kikyo's Lonely Journey 
  • This will be referenced in the future, in the main plot, so it's kind of important.
• Skip Episodes 88 
  • Despite being a canon episode, is just childish comedy.
• Skip Filler Episodes 89-92 
  • These are just average fillers.
  • Filler Episode 90 'Sota's Brave Confession of Love' may be salvageable if you are into love confessions, a lot of girls seem to like it, but it's not my cup of tea.
• Watch Filler Episode 93 - The Mysterious, Lecherous Monk 
  • This is just hilarious and one of the best fillers overall.
• Skip Filler Episodes 94-95 - The Sacred Jewel Maker 
  • These are average and full of plot holes with the main story.
• Optional InuYasha The Movie 2: The Castle Beyond the Looking Glass 
  • This is the weakest movie story, it's just average in my opinion. So I recommend skipping.
• Watch Filler Episodes 96-97 
  • Filler Episode 96 - Jaken Falls Ill - Expands on Rin's character development.
  • Filler Episode 97 - Kirara, Come Home! - It's just hilarious fun.
• Skip Filler Episodes 98-101 
  • These are just terrible and full of plot holes. From now on, most fillers are just bad.
• Watch Episodes 102-128
• Skip Filler Episodes 129-130
• Watch Episodes 131-132
• Skip Filler Episodes 133-134
• Optional Episode 135 - The Last Banquet of Miroku's Master 
  • This is a fun canon episode, that explains a little about Miroku's upbringing but is not essential to the plot. It's quite predictable.
• Optional InuYasha The Movie 3: Swords of an Honorable Ruler
• Skip Filler Episodes 136-140
• Watch Episodes 141-161
• Optional Filler Episode 162 - Forever with Lord Sesshomaru
  • It's an ok episode with some character development for Rin.
• Skip Filler Episode 163 
  • It creates too many inconsistencies with the main plot.
• Watch Filler Episodes 164-167
• Optional InuYasha The Movie 4: Fire on the Mystic Island
• Watch InuYasha: The Final Act 
  • You can watch this season in full as it contains no fillers.

Watch after episode 54.

Optional, takes place after episode 95. But I recommend skipping it, it's the weakest story of the movies.

Watch after episode 135.

Watch upon completion of the original series but before viewing InuYasha: The Final Act.

Watch.

Continuation & conclusion of the story. Watch in full, there are no fillers in this final arc.

Skip.

This special ended up, slightly edited, as Episode 15 of InuYasha: The Final Act

Skip.

These are two commercials for the Shounen Sunday magazine. The first was made around the time that the InuYasha manga debuted and the other slightly prior to the anime's premiere.

Skip.

Written by Katsuyuki Sumisawa, NOT Rumiko Takahashi, this is basically all filler material. Average at best, but after watching InuYasha, you'll feel the quality is lower than what you are used to.

Skip. Continuation of Yashahime: Princess Half-Demon.
