Query: Disappointed

My husband and I recently watched "Upstairs Downstairs" (me for the second time). We enjoyed it so much and wished for more when it was over. I discovered "Thomas and Sarah" and ordered it. We found it enjoyable, however, the ending was not an ending at all. I realize it was proposed for a second season, but really, since it didn't go forward, couldn't something have been written after the last episode to answer the big question at the end?
