Incredibly boring. It reads like artificially crafted school life shoujo and i guess that's the reason behind it's popularity - you can make a list of commonly used setting tropes and check them off as you progress through the chapters. The art is okay. The characters are okay. Their behaviour and reasoning are (mostly) okay. Going by that, it's probably okay if it's your first or second contact with the genre, but in the end "Ao Haru Ride" has nothing special going for it - no quirks, no gimmicks, no surprises. It could probably serve as universal standard for modern romance targeted at pre-adolescent girls, if there ever was a need for such a thing.
