Saw the odd episode of DS9 (Babylon 5 rip-off) and Voyager (the 7 of 9 show), but never really got into the story enough to get the big picture. Saw the odd early episode of Enterprise... but didn't find it very interesting. I like scott bakula, but he'll always be the quantum leap guy for me.
it rather seemed like all the shows after TNG were recycling the same plot ideas, characters and set-ups, but just with new faces.
First 2 movies were of course awesome, as was First Contact. But other than that they should probably be wiped from history by borg. Except the one about going back in time to get whales with an invisible ship!
I got much more into B5 and Farscape. Better, more original sci-fi than anything after TNG.
