One of my favourite sci-fi shows of all time, and the first (but by no means last) time FOX broke my heart by cancelling an absolutely fantastic show. Such a great premise, wonderful characters with fantastic chemistry and great storylines, I was thoroughly gutted when it wasn't renewed.
My OH says it hasn't aged well, but I think he just doesn't appreciate its awesomeness. Love every episode and as soon as it (FINALLY) became available on DVD I rushed to buy it. Also the first time I ever discovered fanfiction, heh.
