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: Spider's Web: A Pig's Tale
Anti-Climax Boss: Ja Rahr near the end. All it takes is a wasp sting and everyone abandons him.
Big Lipped Alligator Moment: Two here: the first is when Walt and Ja Rahr turn the channel on a motel TV, and it starts attacking. Another happens when two silverfish are chasing Walt's car shooting missiles at it. None of these events are referenced at all later in the film.
Fight Scene Failure: In-universe. Walt's auditioning for an action movie, when all of a sudden robots start attacking him and a prop explodes. It takes a second after the explosion for Walt to get launched.
