The Sarah Connor Chronicles rocks.

I just thought that if you were living under a rock or something, and saw some passing stuff for it. I highly recommend you watch it. It's one of the best scifi series to come around for a long time. It also has Summer Glau, and to steal a joke from Kazim's Korner (which also recommends it) it's roughly akin to the XKCD suggestion of River Tam Beats Up Everybody.
