I think there is an interesting tension in the movie concerning the non-normative body, the epileptic body. The filmmaker seems intrigued by it, but also scared that showing too much of it will ruin the "realism" ("gritty" black-and-white images of working class England) of the piece. So he shows the first fit and he shows a little bit of Ian Curtis's epileptic-ish dancing and he shows his "double," an epileptic woman, have her "fits." But mostly he seems to want to "control" the "fits." He doesn't show - only alludes to - Curtis's subsequent fits. I (mis-)interpret the movie-title "Control" (rather than "She's Lost Control") as an attempt to control the epileptic with a kind of "realism." Ultimately the result is yet another reductive bio-pic.
