The difference to SAO is that SAO is indeed still worth watching for animation and music alone, and I hate SAO a lot at this point (well, I hate all anime where all the girls desire only one guy's cock).

If I had to say something positive about this first episode: Thes scene where birb rescued the girl by kicking those bat monsters into oblivion. That felt nice, looked good, and Filo had some real presence there, an aura of "you're save if I'm around". I liked that.
