SAO was pretty terrible, but there are plenty of worse things out there. Probably the worst thing I've ever seen was Chaos Dragon: Sekiryuu Seneki. I watched it as it aired during the Summer 2015 season. It was torturous to watch.
Edit: those of you who actually enjoy SAO need to watch something good. Yes, the first half of the first season wasn't all that bad, but everything after is complete trash.
