Ok, take the Visitor, a great episode with great ating and an intruguint sstory. The "future" stuff works for me indsofar as the Kliongs/ Cardassian/ Space station stuff goes, but then you get to "theDefiant in mothballs" (despite the fact that, as a warship, I highly doubt this would happen" to Jake "rounding up the old crew" It looks they had no lives in the future, save for getting older.) I didn't help that the future uniforms look silly, I would like to think that these characters actually DID things in the future. A lot of the most imaginative premises are hindered by the actual imagination of what COULD happen in the episode. "Parallels" is an example..the premise is really interesting, but the differences from one reality to the other lack scale, scope, or imagination.
