Star Trek: Every Two-Parter Ranked From WORST To BEST

22. Time's Arrow, Time's Arrow, Part II

At times camper than Christmas in the Nexus, the Time's Arrow two-parter is never winning awards for subtlety of any sort. That is largely its charm. I say, I say, I dare say, it has been parodied to perfection, too. Get your best cosplay on. Sometimes the Twain shall meet!

The premise was relatively simple: some rando in a silver jumpsuit finds Data's head buried in a cavern beneath San Francisco and shows it to Data (who still has a head) and Captain Picard. Standard! In practice, things were rather more complicated.

To dismantle and rebuild Data, Time's Arrow and Time's Arrow, Part II took a mind-boggling bend to the 19th century and back via Guinan, Samuel Clemens, and the neural energy-sucking Devidians. This was pure sci-fi fun!
