It had some potential in the first episodes with all that MMO feeling on the fights but after that it feels like a giant filler crawling to its second season. You can basically watch the 4 first episodes put a “and then they developed a government” comment and just go straight up to episode 17/18 that nothing would be lost.
It’s rather boring to watch side characters stories that are just there to give a push to the plot from time to time and Log Horizon is basically that.
At least it’s better than SAO so…be happy I guess.
