This show had its ups and downs but it was one of the very few shows that I never tired of watching and always looked forward to weekly. It may have jumped the shark a while ago but that didn't bother me; it was always entertaining week to week. Just a great cast and a great concept. Stinks that it's run its course since it ain't easy finding good sci-fi/fantasy. Guess they'll replace it with another standard cop show or Chicago SVU something.
