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.
Angst? What Angst?: No one in the film other than the cops seem all to concerned about a psychopath going around murdering people. Barely a day after a violent murder, the friends of the victim all go out to a party. Mr. Royce seems more mad that his daughter was dating a member of a gang than that she was witness to a murder. All of the parents and teenagers seem more focused on trivial things like their social lives and stolen bikes over murders and gangs.
They Just Didn't Care: The lighting crew on this film had apparently never heard of the word "consistency"....
At one point, a shadow from the boom mike crosses over Mikey. Now that's just embarassing.
