Yeah, I've not even finished Kings yet because Hux and I love it so much we don't want it to end.

Babylon 5, if you're looking for something somewhat nerdy, could definitely work. Its plot is planned out through all 5 seasons, and it's so well thought out. It takes about a season for the main plot to kick in, but you don't even realize it watching season one because it's so fantastic that you think that's how the show is, until they surprise you with another level of awesome.

I'm in the middle of season 3 and stuff is getting SUPER serious and fantastic.
