"Storm Front, Part I" and "Storm Front, Part II." As much as I love ENT and am usually pretty underwhelmed or even bored by "11:59" on VOY the Shannon O'Donnell episode at least feels like a coherent, logical story about a woman stuck in an Indiana town on the eve of the 21st century and engaging in conversations with the locals. The Space Nazi stuff that ended the Temporal Cold War was just a mixture of annoying, goofy and downright unpleasant.
