The Final Five Revealed (Season Three, Episode 20: "Crossroads (Part 2)")
"There must be some kind of way out of here…" A lot of shows have teased out big questions, only to offer unsatisfying, anticlimactic answers. When it came to the matter of revealing the identities of the final five hidden Cylons — the genocidal robots in human form who served as the shadowy al-Qaeda analogue for Ronald D. Moore's War on Terror-era sci-fi parable — Battlestar Galactica succeeded like few others. Using inexplicable snippets of Bob Dylan's "All Along the Watchtower" (!) as almost subliminal cues that certain characters were more than they appeared to be, Battlestar solved its big mystery while still preserving its sense of mystery.
