Warning: The following post contains major spoilers from Rogue One: A Star Wars Story and Star Wars: The Last Jedi. If you've seen neither, please avert your eyes.
Star Wars: The Last Jedi is undeniable fun. The latest blockbuster space opera in the 40-year-old series picks up shortly after The Force Awakens, with the Resistance on the run from an incoming First Order fleet. It's a chase that lasts more than two hours -- essentially the most expensive episode of Tom and Jerry you'll ever see.
For the chase to sustain that long run time, the First Order and the Resistance engage in a chess match of sorts. The Resistance pulls off a series of impressive escape gambits; the First Order surprises at almost every turn by being one step ahead. One of the more baffling instances occurs near the beginning, when it's revealed General Hux and his crew can track the Resistance through hyperspace. If you said to yourself, Wow! That seems convenient, Bad Guys! Don't be such a dick. As one eagle-eyed fan pointed out over the weekend, that fancy new tech was a pay-off planted more than a year ago in Rogue One.
