I personally loved it. The whole cast fit the roles perfectly. I especailly liked Vic Mignogna as Tamaki and Todd Harberkorn as Hikaru. Caitlin Glass (the director and voice of Haruhi) really cares about what she does, and that really showed. I think it was excellent.
Plus, I never watched the series with the Japanese voices ^^; I've watched a few clips and stuff, but not whole episodes.
I watched the Japanese version first, and was absolutely delighted with their choice for the English voice actors =3! Beloved Edward Elric (or Vic =P) as Tamaki= couldn't be a better person for it. All the people were perfect!
I really love the english voices, especially with vic as tamaki, to be honest i havent really watched much of the japanese one but the english one was amazing :)
Yup, they all really cared ^^
I really liked the dubs for this show I think all of the voices fit perfectly, I can easily tell Hikaru and Kaoru apart from each other mainly because of there voices.
Which is surprising... when it comes to dubs they're almost never very good.
