Genuine question. On the one hand, the song calls out "violence in movies and sex and TV" as overrated and oversaturated, and praises "good old-fashioned values on which we used to rely," referring to peter as "can do all the things that make us laugh and cry." In the actual show, half the jokes are some variation of X gone violent, or X gone sexual, or X gone really dark with no punchline, mixed with the occasional word play or movie reference. The earlier seasons seem to really adore old movies, especially with their frequent use of showtunes, but the most recent ones are the opposite of old-fashioned, often aggressively trying to be topical, not unlike South Park. And Peter's entire character is that he's unlikable, moronic, and sociopathic, he sure can make you laugh whenever something bad happens to him, but never has any character besides Stewie, Brian, or sometimes Meg made me cry.

On the other hand, the theme song isn't presented as ironic. Nobody is making massive quotation marks or rolling their eyes, and Peter is lifted up on a literal pedestal with no hint of sarcasm. The Griffin family are presented like a semi-dysfunctional but still incredibly close and loving family, and Peter is treated like some kind of cultural touchstone of a bygone era. It kinda makes me feel like the intro is supposed to be some kind of bait and switch where you're expecting an homage to a more classy variant of comedy, only to be welcomed to a bunch of hypermodern and aggressively dark jokes, thus turning the joke on the audience.

Which is it, exactly?
