These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Phone Booth
Darkness Induced Audience Apathy: You know that both Stu himself and the Caller were hard to root for when both of them are established as bad people.
Everyone Is Jesus in Purgatory: The phone booth is a confession booth and the sniper is either a priest or God, to whom Stu is confessing his sins. In the end he is absolved.
Stu himself complains every now and then whenever other people tries to tell him to get out of the phone booth.
What an Idiot: It's fairly reasonable for those hookers to assume that Stu shot their pimp, but it's far less reasonable for them to stand around screaming at someone who they're convinced A: has a gun, and B: just used it to murder someone right in front of them. No wonder serial killers are always picking them off.
