Any episode of Voyager that spotlights B'Elanna Torres is sure to be a standout in some regard, usually (thanks to the always exceptional Roxanne Dawson) for the character herself, because she is more often than not tied up in her own personal journey.
This one has her experiencing a really bad day, which for B'Elanna is virtually a daily occurrence, certainly in the early seasons, yet it's a transitional moment, thanks to the fact that she finally finds herself willing to consider Tom Paris as a serious romantic interest, a development that dominates her role for the remainder of the series.
If you want to like the series, then watching any episode featuring B'Elanna will help you with that. She was consistently one of the most compelling characters on the show.
