This was one of the better arcs of SAO, simply because there was far less chances for the typical SAO bullshit here. No doubt partially because Kirito had a lesser role. Yuuki's death wasn't bad either, even if having thousands of people there to send her off was kind of goofy. But then again, it's a game, so why not. Gamers would lose absolutely nothing by being there in VR, as opposed to travelling physically somewhere far away.
