It was an ongoing story, which was gripping and well told. It is different to TNG of TOS in that sense so I wouldn't compare them and love them all equally.
Voyager tried to mix the two styles and imo failed. The ongoing story was neither gripping nor did I care about the characters. Despite putting them in a whole new quadrant, they had to rely on established enemies and stories to actually make a half decent episode. Yet they threw every established rule, fact or cannon out the window every time the script became difficult. It was lazy writing that had run out of steam.
Enterprise tried to correct this with mini arcs and season arcs. While I enjoyed it, I think they went overboard. Season 3 is almost too much and I found myself wanting a break from the main story arc. I was also very dissatisfied by the finale. Needless deaths and a weak story that rushed the show to a finish rather than celebrating it. The ending should have been more of a beginning, as it was the start of the adventure, so to speak, for many more generations to come.
Anyway, thats just my 2c plus GST.
i think that casting jerry lynn ryan in voyager was a master stroke..................either that or i'm just a perve ........oh your right.....we've established that
