I dunno... Enterprise was so bad.
(And before it, Voyager was pretty disappointing in the story-telling arena; I think sfdebris put his finger on it when he mocks the "Magic Reset Button").
And the new movies are pretty bad once you dive below the action/effects — hey you there, you're the new pilot!
EVERY show always has good, better and best shows.
EVERY show always has a few yawners too. That is just the nature of the beast. CORNY is part of Hollyweird too. Always has been.
I liked the entire concept of the show, the characters, bad guys, aliens and beasties.
There is REALLY only so much story telling that exists in the human experience. It's almost always: love story, love triangles, good-bad guys, good triumphs over evil, struggles overcome. There aren't too many "new" themes to the human experience.
Also, one can only run through the seven deadly sins so many times.
By the time you get to my old age, I REALLY have heard and seen the same ole themes many times. I plan to see them a whole lot more, but human nature's good, bad and ugly doesn't have much new to offer me...just variations on the same theme.
