WHY LISTINGS DO NOT ALWAYS MATCH
Count story parts, not just numbers.
An episode number describes a position in a list, but not always how much content it contains. A two-part opening can occupy one long entry. Moving from episode one to three therefore does not, by itself, prove the second is missing: it might be included in the first. The full title and part labels help distinguish the two situations.
This comparison has a deliberately specific scope: three reviewed openings and the following episode. Choose how your edition presents them, state which entry you finished, and compare the destination layout. It does not shift numbers throughout a series, because that shortcut breaks when further specials, parts or order changes appear.
01Battlestar Galactica
The story starts with a two-part miniseries. ‘33’ opens the first season of the regular series: starting there skips the introduction.
Compare the 2003 miniseries introducing the 2004 series. This is not the 1978 series pilot. If you watch one combined block, check that it contains both parts before moving to ‘33’.
02Star Trek: The Next Generation
The opening is a double-length pilot. When both parts appear as one entry, a list can jump from episode 1 to episode 3 without a missing story.
Look for ‘Encounter at Farpoint’, not just the number. An entry marked Parts 1 and 2 covers the complete pilot. Continue with ‘The Naked Now’ afterwards. Editing can vary between versions.
03Star Trek: Deep Space Nine
‘Emissary’ premiered as a feature-length pilot and was also broadcast in two parts. You do not need to repeat the opening if you already completed both in one video.
This case only covers the transition from ‘Emissary’ to ‘Past Prologue’. It does not convert the entire season or establish equivalence between cuts, dubs or timestamps.
