Blood Sister's finale: is the applause sarcastic?

Undecidable tone as the metaparody's native climate. The film's own ending is "unclear in a way that's supposed to be rich" — a possible-redemption undercut by a discount-Harley-muffler sign on the horizon — and its audience mirrors the ambiguity: you can't tell if the applause is sincere or sarcastic. That undecidability is manufactured and prized as sophistication here, but it's the exact condition that turns lethal in 178, where whether Himself "always meant it ironically" becomes unverifiable once viewers start dying. Irony's proudest effect — you can't tell if I mean it — is the theme's deadliest liability, shown here still wearing its cleverness.
