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.
Crowning Music of Awesome: The Zuckers and Abrahams were actually disappointed when the film ended up with a genuinely good score, rather than a cheesy one that would add to the parody. They probably shouldn't have hired Elmer Bernstein.
The film itself has inevitably had this effect on Zero Hour, the major inspiration for its plot and many of its lines. It's downright surreal watching that film now and seeing lines like "I picked the wrong week to quit smoking" played completely straight.
The Scrappy: The constant Troll in the airport tower who eventually pulls an important plug at a vital moment, apparently because he wants to make life harder for everyone. It's even worse when you consider that he manages to get away with everything. But then, animosity toward his character is probably supposed to be the point. Still doesn't explain why he gets away with it, though.
