I was kind of bored throughout season two of SAO. Then I rewatched season one and realized it was actually pretty average. It was great when it was some of the only handful of anime I had ever watched, but having seen legitimately good things that handle both drama and action better since, it doesn't rank all that high. Even among the "trapped in a game" trope, anime like Log Horizon and Overlord handle the basic concepts in a much more interesting way.
