It's pretty darn good, just keep in mind the first season's best episodes are the first two and the last, since those were the only ones written by Gen Urobuchi. The second season has the better soundtrack, but it sort of fizzes out towards the end. Also, Inaho becomes the definition of overpowered. You thought Kirito was OP? Second Cours Inaho is a whole new level. Still highly recommend it, one of my favorites!
