^^desperate times call for desperate measures, I guess.
Voyager tried to be intellectual with high concept stories during the first few seasons and veiwership was still declining. They gave us "Scorpion", with the Borg and action and for a brief moment the viewership increased. They tried every trick in the book to get us to watch while still having to answer to their slave masters at Paramount.
Trek fans feed back was too erratic for them to really understand what type of show Voyager should be. For every 5 fans that liked it, there were 5 more that didn't. Who do you listen too? B&B did the best they could do at the time, they listened to their gut. Did it work? We still don't know because some Trek fans are rediscovering Voyager now and liking it better than before while others still don't.
Voyager was a show that wasn't going to make everybody happy no matter what they did. So the show had little choice in becoming whatever it became.
