For the people that truly love this show then don't read this.
I decided to get the series after the hype I was hearing. Also after reading the manga and thinking well the anime must be better! No I was wrong so wrong. The manga and anime are basically the same in every way that also goes double for how I feel about them. I find it blah. I can watch it but I don't feel attracted to any of the characters.
Haruhi- For a character that "suppose" to be exciting I find her to be boring and as a run-of-mill character.
Kyon- His extra normal so he's the strait man in the story, so for him normal is okay.
Itsuki- He would be an awesome character if he had more chance to develop more.
Mikuru-Walking fanservice, that's I'll I have to say.
Yuki- As characters go she's probably the most developed character of them all (in my option)
So if I had to rank it. It would be in the "watch when your sick and there's nothing else on" kind of show.
