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.
Nightmare Fuel: Those goddamned "chipmunks" from Disaster Movie.
Padding: Meet the Spartans' total runtime is 86 minutes, but the actual movie (before the end credits) is between 69-70 minutes.
Shallow Parody: Not surprising, since the producers have admitted they generally just watch the trailers and go from there.
Special Effects Failure: The effects are just as cheap as the parodies they try to do. Disaster Movie especially.
They Just Didn't Care: To a near jaw-dropping degree. Jokes are usually painfully obvious, show no knowledge of the subject being parodied and are quick to rely on toilet humour, gay jokes and irrelevant pop culture references.
