Just spent the last couple weeks plowing through Hajime No Ippo, Shingeki no Kyojin, Tengen Toppa Gurren Lagann and Monster. I'm thinking of trying either Gintama or Cowboy Bebop next.
At the moment, I'm looking for something with a lot of action. Length doesn't matter, but I'd prefer a completed anime over an ongoing one.
