A couple caveats before I begin:
*I am not in any way anti-sub,in fact I have rather enjoyed the subs of other series such as Excel Saga,Neon Genesis Evngelion and the Tenchi movie Tenchi Forever.
*Undoubtedly my opinion is biased on the fact that I came to the sub after so much time watching the dub.
*This is not any way construed to be official,just my opinion so you can agree or disagree.
So here goes.
On the whole I was looking forward to watching the sub version of Inuyasha after reading how much enthuasitic reviews subfans gave it.After the first
several minutes I was tempted to turn it off and go back to watching the dub.Having root canal during a thunder storm would have been more pleasant.
Then again I have to admit the ep.I watched was from the first season and actors are still trying to find their characters.Though I have to say by this
time they should have looked in the Lost And Found,especially for Kagome and Inuyasha.They were the two worst among the Japanese cast.
My opinion of the cast:
*Kagome=She came across as sounding way too youngish at the beginning but showed a bit of improvement toward the end.The only other problem was when her seiyuu was doing the Next Ep. Preview.She sounded like she had too much sugar or was over caffienated when reading the preview.I mean it came across like she was auditioning for the role of Excel in Excel Saga.
*Inuyasha=The guy needs to take remdial acting lessons.His entire idea of making Inuyasha sound tough was to speak very loud and very fast.The word FLAT comes to mind as in he could have gotten kicked out of the army for having a flat voice.
*Miroku=The second best of the entire lot.
*Shippo=Well Shippo is Shippo so it would be amazing if the seiyuu playing him could have missed.Shippo in short is such a gimme that you would have to be really bad to not do him well.
*Kikyo=The best and only reason,IMO,to watch the sub version.The seiyuu who did Kikyo really captured her essence well.It was different from Willow
Johnson's portrayal but still you could sense the contradictions in her character.It's too bad that the Japanese version had to center around Inuyasha and Kagome as a Kikyo and Miroku series would have been hundred times better.
Note:I haven't seen any eps with Sango,Kagura or Naraku or Kagome's friends and family in them yet so can't say wheter or not my opinion of them would be any different.
Recommedation=If you must watch Inuyasha subbed make it one that is heavily Miroku or Kikyo.In general if you plan to watch any anime subbed
make it something like Neon Genesis Evangelion or Original Dirty Pair.
IMO the only way to watch Inuyasha is dubbed.
