I liked SGU plenty. The characters were a little less likeable than prior incarnations, but I felt that it tried not to be as trapped by cliche science fiction tropes like SGA tended to be, and SG1 tended to parady (the latter being preferable). In some ways they failed, and others they succeeded. I honestly felt quite bad for Eli in the final ep and I couldn't stand him through most of the series - too many shades of Wesley Crusher with that one, but not quite as annoying.
And yes...Lt. James..."I'm up here!"
