Sword Art Online was an anime that I did not particularly enjoy. I found many aspects of it either annoying or plain stupid.
Nevertheless, I still watched the Specials. I found that they were much more enjoyable than the anime itself.
Since these are pretty much OVAs, they don't have any particular storyline: instead they are presented under the form of news bulletins.
What I really liked about this is that most of the points that I did not enjoy in the original anime were drawn out and made fun of. Basically, the anime was making fun of itself. It was a little ridiculous, but I really enjoyed that it was mocking SAO in essence.
The art was decent, and I can understand that some might not like it, but then again, chibis are really an acquired taste.
Overall, I can say that I enjoyed this more than the original, though it is by no means a noteworthy title.
