I think Attack on Titan is on Netflix? Idk.
Also, these aren't on Netflix, but I'm sure they're on crunchyroll or hulu: Tokyo Ghoul, Space Dandy and Zankyou no Terror.
Watch Zankyou no Terror here.
Watch Tokyo Ghoul here.
And Space Dandy airs on Adult Swim. The two I linked only came out recently, so there are only a few episodes.
Edit: Oh, didn't see that you wanted
English dubs. Well, Space Dandy and Attack on Titan are the only ones that are dubbed on my list. Sorry.
