I sometimes wonder what my favorite series of star trek is.. whenever I watch DS9, it's my favorite, when I watch voyager, it's my favorite, when I watch tng, it's my favorite.. I think, really, they're all my favorite. Putting myself in those world's, is one of my favorite things to do. It doesn't matter where I'm at, just that I'm in star trek. Exploring life, the future, and all of the possibilities of humanity there in.
DS9 stands out to me as a slightly darker story. I love that the whole series stands out as a whole arching story, but there's episodic tales lightly tossed in between the whole. Its simply an amazing showcase of what star trek can be. I find that there is more relationship between the ENTIRE cast, as opposed to the other series of star trek, and it really brings the stories and episodes together, to fully tell this awesome story.
