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: My Cousin Vinny
Designated Villain: Surprisingly, for a legal drama, averted. The eyewitnesses and prosecution honestly believe that Stan and Bill are guilty. Vinny's defense is based on demonstrating the honest mistakes the witnesses made. When Vinny conclusively proves that the prosecution's evidence is faulty, the prosecutor immediately moves to dismiss.
What an Idiot: Following their arrest, the boys make the mistake of not confirming what they're being charged for as soon as the police pick them up and sit them down. Of course, they shouldn't have said anything to the police in the first place.
