Cm James Sisko: He's flawed, he's deliberate, he's tragic, he's warm. Not aloof like Picard, nor as diplomatic. Not gung ho like Kirk, more thoughtful of consequences.
Odo (My chihuaha-minipin- rat-terrier mix is named after him) The interplay between Odo and Quark is reminisecent of the interplay between Spock and McCoy, only with different variables. Odo's difference from Spock is that while Spock chooses to ignore his humanity, Odo, who's natural state is formless, chooses to explore the why's of humanoid life. The difference between Mc Coy and Quark is that McCoy' is the epitome of integrity and honor, and he defends humanity. Quark wallows in his depravity and greed, but both are curmudgeons, and you grow fond of the characters.

Star Trek is like any other series, it's popularity will wax and wane. The direction it goes is out of my hands, that is up to the producers. I liked the prequel to Enterprise, I think exploring that area of time may eventually beome as charted as the rest of the Treks. After a while it may get old. Then I suppose a distant future would be the next frontier.
