my favourite was DS9 cuz of all the interesting characters, also the USS Defient kicked ass...but i really liked the story and how it played out from the bjoren prophets to the dominion war(which i always thout the star trek series was missing, 100s of starships battleing it out), which proved that starfleet wasnt all powerful as they thought they were. TNG would be my second choice. But i couldnt stand Voyager i thougt that characters where dull and boring... since voyager it seems that for some odd reasion that every starship now has an extremely hot chick on board that adds nothing to to story but tring to get high ratings from the geeky population. Enterprise i cant stand either, it look good from the begining but it seems the story isnt going anywhere.
