I absolutely agree about Asuna. I find her "perfection" way too bland. The sudden jump from her dark initial persona to the perfect team leader with amazing household skills was also too abrupt because not a lot of time was used to show the transition.

I also find the entire Yui daughter thing extremely annoying. SAO would have been much better without her. She kind of represents everything that is making suspension of disbelief harder to achieve.

That said, I am still looking forward to the next arc. I believe people who hate SAO will still hate that because it has more of the same stuff (it is a light novel after all, which is almost trademark formulaic for each novel, with very few exceptions), but the people who liked the good parts of SAO will probably like it. For those who might get interested because of this fact, it has guns.
