欧博官网What is the meaning of "it insists upon i
The other users are mentioning the use of the phrase in the context of The Family Guy to tell a joke. These answers are correct.
But "it insists upon itself" does have meaning beyond the joke.
It's essentially a way of saying "look at me", that the film is self-absorbed and self-conscious, that it doesn't really acknowledge any kind of lightness or irony, or any sense that it's mere entertainment, or any acceptance that it may be flawed; that it's pompous, self-important and relentless.
The way this construction works is that were someone to say "but it's only a bit of fun" the film would say "no I'm the best", it would insist on how wonderful it is, on itself, just like a pretentious person.
The reason this construction has been chosen is that it's in a register used by hack critics. For example it uses a form which is grammatically precise but semantically awkward and ambiguous, requiring work on the part of the reader. The intention is to demonstrate the apparent intelligence of the writer. (Apparent at least to the writer!)
