It's your average adventure anime, with average art and story... But absolutely no suspense/intensity or anything that gives a sense of insecurity.
It's been clear from ep 1 they were no risks in PKs, bar losing some stuff and come back to Akiba.
At least SAO PKs were followed by IRL deaths.
But maybe they'll do something about that weakness soon.

Now that I wrote all of that, it was still pleasant to watch and spend some time. Some kind of MMORPG slice of life.
