That little Season 2.5 they did last fall wasn't very good, and things started a bit slow this spring, but everything picked up to a fantastic pace for the last ten episodes or so, and the finale was kick ass. I've seen every episode, and SWMBO and I will definitely be watching all the rest.
BTW, has everyone heard that they're planning three more seasons of sixteen episodes each? Apparently, they're going to do like they did this spring, just show them all in a row with no breaks at all. But they're only showing them in the spring, which means we have to wait until February of 2008 to see new episodes. But, they say that the show will end properly in spring 2010, which is cool. It makes me feel like they actually have a plan and aren't going to just milk it as long as they can.
