I think the one thing that hurts BoBw when both parts are together is the re-use of footage of the Enterprise getting attacked at the end of part 2. It is all re-used footage from part 1. BoBw was the best of the TNG two parters, but one thing TNG never got right was part 2 usually sucked when compared to part 1. DS9 was better at pulling off multi episode arcs than TNG. One thing that would have been cool to show with BoBw would have been Family as a preview to the next season.
