Those recent single-part stories have helped put these bloated trilogies in perspective. It is a good direction for the series, as even sagging middle installments like this get to spend/waste time on entertaining fluff like Archer and Shran's sub-kal-if-fee battle and Tucker and Reed playing Romulan Crystal Maze for their lives.
As satisfying as it is to see the Federation coming together (even if the oncoming cancellation dulls the optimism), it's disappointing that they feel the need to keep re-using old plot elements like the cloaked ship detection grid. I suppose after 700-plus episodes there really are no new frontiers left.
