Looks like I'm in the minority when I say...
DEEP SPACE NINE was the best of the series. Sisko was a man's captain, unlike them wimps Picard, Kirk, Janeway and Archer
The final episode of ST:TNG (7th season) was called "All good Thimgs..." and had my favorite character of all the series Q (played by John DeLancie) which brought the series full circle from start to finish.
Voyager was horrible...can we say "Gilligan's Island: Space version"? Find a way home only to have something go wrong. Gilligan was doing that to the Skipper and the Professor all the time
And I agree. Enterprise was a wreck though the storylines improved in the last season however showed a classic example how NOT to finish off a series...what a snoozer
