Sidequels

Watching the latest Bourne movie today, it struck me how cleverly it was plotted in relation to the previous films. The Bourne Legacy was not a sequel nor a prequel, instead its timeline overlapped with the others. I propose to call this a sidequel. I considered paralleloquel but that hardly rolls off the tongue. Whatever it's called, I recommend it, if only because the editing was slow enough for mortals to follow the action sequences - a radical departure from the previous films.
