@theblue: Just wanted to say that this is basically the exact same situation I found myself in for a LONG time. Up until earlier this year I basically hadn't watched anime in years, thought a lot of what I heard was coming out sounded bad, but still got pretty defensive of it. Toonami/Adult Swim's anime block basically WERE my childhood/teenage years.
@grantheaslip: Kill la Kill was one of the shows that got my back into anime as well. I met a bunch of people at my school in a past year (an Anime/Video game club that was shockingly fun) that were way into anime, while I hadn't watched any in YEARS. Attack on Titan seemed like the last big thing, so I checked that out and was almost instantly turned off but tried to keep going until episode 6 where I couldn't take the "dark for dark's sake" anymore. Then I started talking a friend about this, he agreed, and told me to watch the new Jojo anime. And then... I enjoyed an action/shonen anime in a way I hadn't since Toonami. J-Stars Victory Vs also played a part in this, but I then got a Crunchyroll subscription (which I agree is a BIG part of watching anime again, searching for fansubs in frequently sketchy areas of the internet was never really a good time) and have been having a GREAT time. Kill la Kill and Log Horizon were things I really latched onto, with Aldnoah.Zero (which I started watching solely because Hiroyuki Sawano was doing the music) in the current season also being incredible.
As someone who tried real hard to like SAO, I would recommend stopping and just watching Log Horizon. SAO gets... real bad.
