Well it sure was a cool show, and I had a hard time coming to terms with its ending, which is THE suckiest ending I've ever seen : I just couldn't believe it when I first saw it, even though I knew the end would come pretty abruptly, that's just horrible. It was beginning to become more complex and interesting, with a real arc... Kind of like the Joss Whedon shows : the first season was a lot of standalone episodes and character developpment, but the second season showed premise for arcs and complexity. What a shame, really, what a shame. It could have become a very very good show.
But because it only sorta had that one season, the only memory I keep from it is like "Well, that was really entertaining". I think I'll buy the DVDs this summer though.
However, now I've come to grip with the way it ended, I don't really really miss it the way I miss Pushing Daisies by example, and that's because Tru Calling was cool and fun to watch but never had the time to bloom.
