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.
Narm Charm: Much of the movie, some of it deliberately, but probably the most straight-up example is the "Magical Video Game Battle" between Lo Pan and Egg Shen. It is both awesome (as intended) and hilariously ridiculous.
Despite how incredibly fake and stupid it is, Thunder blowing up like a balloon somehow works because of how funny it is.
Society Marches On: Imagine the thug pulling out the revolver in an airport nowadays. There'd be a whole army of TSA agents on him in an instant.
Special Effects Failure: Given the movie is a parody of magical martial arts movies, some of it is bound to be intentional.
Thunder's mentioned explosion.
The monsters aren't very realistic looking and are obvious effects/men in suits.
Unfortunate Implications: To judge from this movie (not that anyone would...), Chinese-Americans are all well-versed in ancient mysticism, martial arts, and gangland warfare, regardless of whether they're bus drivers, restaurant owners, or actual gangsters.
