indirect revenge movies are silly
unless you kill the true perpetrator as a final act, your revenge is pointless.
here's what filmakers want to make us believe. that a sociopathic person can be made to feel awful by the loss of a loved one.
the reality is, if they had any sort of fondness for the dead person, they'd get over it very quickly. that's why they're sociopaths.
you know what the ending would be like if you turned on the reality switch? she'd tell him "just kidding" and he'll just shrug and say, "that doesn't bring back your dead daughter, dumbass"
