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.

1 Reply-blam!-ing school days. That thing was what put me off of anime. Don't watch it. Seriously, DONT. Bad story, bad characters, it's just bad. Trust me. If you don't believe me watch a review.
