For a while I've seen SAO being one of the top ranked manga with only 11 chapters, curious I finally decided to read it and... well... I'm seriously disappointed. The story is good but ridiculously undeveloped. I mean... I know that this is annoying when two characters need ten volumes to kiss but going from "I almost know nothing about you" to "We are a married couple with a child" in 50 pages is a bit too much. Same thing for the story ending in a way that looks like someone threatened to kill the author if he didn't ended the series in two chapters. The can be deemed correct depending on you tastes but you can't honestly say it's outstanding. Surely if I were to note this manga I wouldn't give it more than 5/10.
I've read the posts of some other people stating their own disappointment and came to wonder if, although the manga is mediocre at best the anime/LN would be worth watching/reading. So could someone who watched/read one or the other tell me about there quality and the differences between the three versions. My main question being : is the action so absurdly fast-paced in the other media or do we get a little character development?
