Glad to hear that about Tokyo Ghoul, one of the animes i've got under observation and might just pick up!
I definitely think it's worth picking up at least to see if you like it.
About SAO and ALO etc etc etc
ALO is somewhere between terrible and mediocre and i don't know how i managed to watch it but i will never be able to forget it for a few reasons like the scene with the "big bad" towards the end when certain things happen. Also ALO really did its best at ruining Asuna from a pretty awesome character to average lovestruck damesel in distress #44. I would probably be less harsh on ALO if it didn't come directly after Aincrad and that arc because it was phenomenal. The contrast between the two is just massive and really did not do anything justice. Gotten even more harsh towards ALO by each anime i watch since SAO was the first anime i watched in years.. will judge the two arcs seperatly forever because i can't let the first half get ruined by the.. other half.
I don't know if "ruined" is how I would put it. I'd say... wasted. It's not that the character is necessarily worse for it or that she went OOC. She just had potential and was put on ice for the sake of a really shitty plot device.
