It had good art, sound, the character designs and personalities were great. It was also a great concept, the whole idea of being trapped in a game and all.
It had great fight scenes and all but my greatest issue with it was that it seemed rushed and hallway through the show, it transformed from an action anime to a love story, it became a little but dull for a while.
There are some other cons but nothing to much to ruin it. It was still a good anime.
