I've seen a few episodes of One Punch Man on Hulu, My daughter raved about it, it's one of her current favorites. We watched it while she was on Christmas break from college. I think you will like it weyrbunny. I can't really described it, except to say that is zany, a bit off the wall, but has some pretty good action scenes. To the best of my knowledge, it has not been dubbed yet. The episodes we watched were all subbed.
Dimension W looks potentially interesting. I have seen Pyscho Pass on Netflix. I was hoping that at some point that Darker than Black would be on the Toonami block, but it appears that Funimation no longer has the license to DTB. I wonder if they will ever show Ghost in the Shell: Arise. That show was on Netflix streaming, albeit as subs only.
