You gotta love SG-1 for this reason. It starts out slow with hard science fiction as the backbone, but as they get a bit more soft, the series really takes off. The first season is almost unbelievably frustrating in that it showed no character growth or development at all. You could watch any episode in season 1 and watch it right after a later episode and not miss a thing. They go through the gate, find some humans that speak english, daniel matches their culture to some ancient earth culture, some plot device happens and they return home without any new technology.
Then at the end of season 1 they plan on shutting down the stargate because it costs too much and they haven't found any worthwhile technologies.
When I show my non-SG1 fan friends this series for the first time I always show the first two episodes, then the second to last and final episodes of season 1. Season 1 is a filler season. In the final episode we find that Teal'c (the first prime of apophis) believes that the fastest the ships can go is 8 times light speed. We find out later that this number is way off. That episode also introduces zat guns, which are pretty much stun guns that can kill and disintegrate. These guns are a fun little mechanic they use often in later plots.
It's a wormhole series. It really has some great episodes, and if you haven't watched it yet you totally should. I really love how later seasons start integrating earlier technologies into our modern day world as new earth technologies, as well as the super secret stuff they keep for planetary defense.
gotta be a soft man for this reason. BTW, atlantis followed this strategy and was great as well, but SGU is going for the human drama side and is gonna fail because the characters ain't that cool and they really haven't gotten a story to tell yet. Voyager was bad for it's own reasons but at least they had conflict. SGU is trying to be BSG without cylons and failing horribly.
