Yes, I miss SGU. The 'stones' were a mistake, just as Atlantis managing to get back to Earth so soon was a mistake.
Voyager, Atlantis, Universe - one day someone's going to do the 'stranded far from home' story well.
That being said, Universe was definitely getting better with season 2.
A shame that there was no season 3, and an even bigger shame that there's no new SG fullstop now......
