An anime about people trapped in an MMO. Now where have I heard about that before?
When two things are released in quick succession, with very similar premises, and you know that one of them was good, there are pretty much two possibilities for the other. It’s going to be terrible, or it’s going to be amazing. With this in mind, I watched the first few episodes of Log Horizon with a cautious, but open, mind.
Log Horizon is definitely the latter of the two options.
