I love them all! All the BLEACH OPs and EDs are unique, amazing and epic! No hating on any of them.
But I had to choose Shoujo S here. The song is perfect, awesome, flawless and wonderful (SCANDAL is one of my favorite bands) but I chose this opening because of the animation. I really disliked the girls dancing in that OP (OMG! That was truly disgusting. Was it necessary to disturb my mind with Orihime's vulgar and obscene moves? No, right...)
However, I don't hate this OP, it's just that is my least one, as the pick says.

I don't lie this opening... All the openings are amazing but I don't like the song in this one :( I tought it was horrible compared to the ones before!

BTW, Opening 14 isn't called "Naihi Shinsho".
It's actually called BLUE and it's performed by JRock band ViViD.

And Opening 1 isn't called "Orange Range".
It's called *~Asterisk~ and it's performed by ORANGE RANGE

Oh! And Opening 2 isn't called "Uverworld".
It's called D-tecnoLife and it's performed by UVERworld

i like Opening 3- Ichiru no Hana its totally rocking.....................heh ehh eeh

@KEISUKE_URAHARA
The question was the song you didnt like not the song you liked most, i didnt read the whole question and chose my favorite too but i just read it again and realized it, haha.

This was the one I liked least - though, in retrospect, I liked pretty much all of them, anyway, except this one - it kinda annoyed me. Lol.

Wrong picture from the opening 3! It's an image from opening 4 Tonight....

@lisseth vulgar and obscene moves from orihime ? Are you dumb or something because rukia was also doing the same moves so why do you only point out orihime -_-
-Also i dislike this . I just didnt like the song or the video
