It's an amazing anime. Personally, I like the fact that it's fast paced, but I was also surprised at first. The storyline is pretty good at the beginning, but then became a bit bpring during ALO. I loved the fact that they put romance and action together, and after SAO ended it seemed like a forbidden romance between Kirito and Asuna. The anime was pretty awesome. Other than the fact that after the 13 or 14th episode it started to become ALO, which had nothing to do with most of the beginning, and it sorta ruined how the SAO built up, it was overall pretty good. They animations were really clear, and it seemed like they were actually in a video game, but also in the real world. The music was the really good! It matched the scenes perfectly. For me, this is one of my favourite animes, and I think everyone (who likes the genre) should watch it. FYI some parts of it may be a bit confusing for some people, but I found it easy to understand lol.
