There are a handful of episodes in Season 2 that illustrate why many ST fans were disappointed with Voyager and fairly labeled it TNG-lite. Just when Voyager should have been getting its sea legs as an established series and boldly going where no ST series had gone before, we get regression and repetition.
1. "Threshold" The much-derided salamander episode is just a rip-off of the TNG episode "Evolution".
2. "Projections" Welcome back, Barclay for the 1st of 6 times throughout Voyager.
3. "Death Wish" The return of Q and a cameo by Riker. Why are the producers so determined to remind us that we're watching Star Trek? You think we don't know?
4. "Prototype" and "Dreadnought" are only four episodes apart and are basically the same B'Elanna learns about herself while saving the day from self-aware machines episodes. In both cases, the threat is unwittingly her fault. In addition to the blank-faced lack of creativity, we see that, instead of the nonconformist, don't-tread-on-me, aggressively defensive B'Elanna promised in Caretaker, we get a frequently chastised adult-child desperate for Janeway's approval. Janeway (a pedantic, lecturing, authority figure) should be the exact personality B'Elanna recoils from in disgust and contempt. Instead, she tucks herself under Janeway's wing. The most combative B'Elanna can manage is mild sarcasm and sullen brusqueness and never toward Janeway who she treats with obsequiousness.
These episodes, while lacking in creativity, also demonstrate the final nail-in-the-coffin failure of the idea of ongoing Maquis/Federation conflict as an essential source of drama to distinguish and propel series and, with it, the abandonment by the producers at any real attempt to establish Voyager as anything other than a thinly veiled remake of TNG. This surrender is finally bluntly admitted at the beginning of Season 4 for by the departure of one Delta Quadrant character (Kes) and the pushing of the other (Neelix) into the background in favor of introducing a "reformed enemy" character from a TNG species, The Borg.
