Yeah, it’s a definite departure in tone. But stick with it. It becomes a more serious rendition of the franchise, but it’s just as engaging.
It not only keeps the overall spirit of the franchise going, it revitalizes it because of the set and setting. Where SG1 and Atlantis have humanity becoming virtually indestructible gods through their new technology, EVERYONE in SGU is vulnerable.
It’s really unfortunate because the show was canceled right when it was finding it’s feet.
