Looked up Gurren Lagann. I kept getting it confused with Neon Genesis Evangelion. Yea, that show looks pretty awesome. Does it have a good dub?
Yeah, the dub is pretty solid. And has Steve Blum as this guy:

It did air on Syfy a few years ago, but Syfy edited everything to shit (this happened with pretty much every other show they aired, for that matter). The best was when they cut out like half of the final battle of the series. Gotta fit dem THREE commercial breaks in.
