Colony Drop: The premise of the movie. Eventually averted.
Gratuitous English: In the second half of the movie, two characters speak a few complete sentences in English, and just about everything the computer says is in English.
Non-Serial Movie: Subverted. 99% of the movie is set in an After the End alternate universe, but at the end Tendou goes back in time and alters history, creating the T.V series timeline.
And in an odd subversion of the Timey-Wimey Ball, this actually makes the plot slightly less confusing by explaining some of the plot points of the series itself (i.e. how Tendou got the Rider Belt and Hiyori's obsession with drawing bug-winged people).
