My favourite anime ever! I watched it like four or five times already:) I love all the host club but especially Tamaki and Hitachiin brothers:) I love how Tamaki cares about the people around him although he does stupid things sometimes. I love how Kyouya calculates everthing in terms of merits but it isn't exactly real and how he wakes up as a demon king in the mornings like myself:) I love how Hikaru and Kaoru deceives everyone(especially Tamaki) everytime they are bored. I love how Honey and Mori understand each other and care for each other and lastly I love how Haruhi calls the host club rich brats when she is angry and how she doesn't care about much things:)

I loved this anime with all the different -fun and crazy characters. It was so sweet/ funny! I didn't like the ending that much, it didn't wrap up - felt like a cliff hanger...but its still AWESOME!
:)

Loved the anime.

Though I always prefer manga over anime, I just love seeing the chara being animated ^^ Especially Hikaru & Kaoru, love it when they speaks together/at the same time.

Nevertheless, Suzumura Kenichi (Hikaru's voice actor) is my favorite seiyuu ^o^/

A little comment 'bout the ending; The Tamaki/Haruhi part when they were falling. I was like; "Oh no.. please don't kiss.. please don't kiss... PLEASE DON'T!! Woah thanks godness they didn't kissed."

I love both the anime and the manga! Tho the anime adds some more parts to the plot that make it funnier, like the blinking arrow on the vase.

Ye the first time I watch Ouran, I was like; why the hell are they pointing at the vase? It's so annoying! >_<

This is a great series. I read the manga first and wasn't extremely into it but the Anime took it to another level. Great adaption. Loved the characters personalities. especially Tamaki, he is so hilarious. I love the seiyuu too. It's funny to hear him as Light Yagami all serious then cross to Tamaki being all... Tamaki-like. It's a very popular series and I know why, it wouldn't be popular if it wasn't good. I'd love to see another season, whether that would happen or not I don't mind.

OK, this thread slipped throught for a while, my bad.
