Ryll is right. You need to watch a bit more to be able to have a fair grasp of what is out there.

That said, I do not think SAO is bad, nor is this show. People just have a tendency to bash on things they do not like, and exaggerate as if it was the worst ever or something. SAO or this really is not, and my words at least have some weight having seen 1300+ anime titles, including the horrible ones.
