Here's a couple of unpopular opinions I don't think I've mentioned in this thread before:
-I don't like the look of the Voyager very much. It always looked like a shoehorn or a garden spade.
-While I usually love Jerry Goldsmith's music (His TMP and Planet of the Apes scores are amazing), I've never cared for the VOY theme. It's not heroic or majestic like the TMP/TNG theme, and it never really seems like it gets going. It's just kind of... there.
I don't like the Intrepid-class design either. It just looks completely generic and uninteresting.
As much as I like the Sovereign-class design, I hate that it started a trend of eliminating the saucer/neck/stardive designs in Star Trek.
