Voyager last 2 years become .....the what's wrong with Seven of Nine this week show.
My issue was more with the whole "ship is in danger due to X thing" plot. But basically every late Voyager episode which wasn't a "character focus" exercise for Seven, The Doctor, or occasionally another crew member. These episodes are lame because we know that whatever tension takes place over the course of the episode, it will all be resolved by the end of the episode (or two-parter, in rare cases), meaning the show is essentially faking us out.
Trek had always thrown out episodes like these on occasion. But no other series - not even Enterprise - fell back on this plot device as much.
