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: Super Size Me
Anvilicious: Even if you like the film, it's hard to argue against this one.
Captain Obvious Aesop: Fast food is bad for your health. The film admits that everyone already knows that, but attempts to show that it's worse than you might think. The doctor at the beginning says that he expects Spurlock to gain some weight, but after a few weeks is begging him to stop the experiment for his own safety. The experiment as a whole just glues together a larger message about making smart food choices.
Never Live It Down: The film became this to McDonalds. Even if you haven't seen the film, you've probably at least heard about the sequence of Spurlock struggling to finish his Supersized meal and vomiting it in the parking lot.
Some Anvils Need to Be Dropped: While there's no real denying that this is a bit of a Captain Obvious Aesop (excessive fast food is harmful to your health? Really?), a case can be made for this; the movie does spend a bit of time pointing out the reasons why this is the case, some of which are not what you'd expect.
When Morgan ate his first Super Sized McDonald's combo and promptly vomited.
The huge hair he found in the parfait.
Strawman Has a Point: While people may disagree with the movie's argument that the blame only on the fast food corporations and not on personal responsibility, the movie does make clear that the actions of said food companies are not helping the situation.
Also, the movie goes into detail on related problems, such as the relative lack of heatlhy food in school cafeterias (or the ease with which a student can have a lunch consisting of, say, a tray of french fries), or the difficulty that someone living in the city might have with actually buying significant quantities of healthy food if they can't afford to travel far or lack much free time outside of work.
