Query: Really Great Series!

So why did I only give it 4stars. I was personally disappointed with some of the endings. The acting was fabulous. The sets were good. The initial story line was gripping and many of the conclusions were outstanding. But a few of the conclusions left me saying "Huh? Did they run out of money or ideas?" Still I like the series and would be future seasons.
