The art style is nice, it's even a bit better than the 1st part. Story as in a rpg has become quite common after .hack however, it kept some form of uniqueness to it, with it being more than just the game. Still, save the princess scene like SAO 2 is kinda over done, both in anime and games. Not that I mind, bc it sets a goal to work 4, 4 our hero. The characters were good, not super unique, but quite normal from what one would expect in a anime. I don't think the characters had big realistic elements to them when it comes to their reactions, but I don't thinkmy view upon it is that of importance,
BC I compare it to my own life.,. Nyeah.,.

I kinda liked this anime,
however, with the anime just ending without a conclusion
and it being over 8 years since the last episode,
I'll guess I have to read the manga to know the full story.,.
Really sad, BC it would've been much better if it didn't end like this.

I guess the largest problem with the anime is the sudden end,
not really with the quality from it itself.
