The narrator is a character in Arrested Development, just as the narrator is a character in Our Town and Into the Woods, and to a degree in Pippin, yet in those shows (like AD) the role is not an official part of the fiction. In other words, he’s not an “in-story” character, such as the narrators in classic films To Kill a Mockingbird, All About Eve, A Letter to Three Wives, The Shawshank Redemption, Mr. Blandings Builds His Dream House, I Remember Mama, and so on.
What the narrative in all these examples has in common is that it is vital to the storytelling, and the tales would be diminished without them. Indeed, just about every single novel has a narrator who tells you motivations and what characters are thinking, and we accept that because that’s what books are like. Why shouldn’t a TV series play with conventions and use the same formula? The Wonder Years had narration too, now that I recall; and though I’m not a viewer, I’m pretty sure Desperate Housewives used it too.
So let’s discard the idea that the use of a narrator is somehow inherently bad for storytelling. It’s ludicrous. You may not like the innovation of having such a narrator become integral to the comedy, but quite clearly many people do, and part of it is the innovation of such a nudgy, omniscient and sometimes even petulant (“she’d best watch her mouth!”) narrator. Plus, Ron Howard does a great job. I can think of precisely one instance where the narration ruined or overplayed a joke, and that’s the “Hey! That’s the name of the show!” line in the third season.
Gosh one might as well deride Peep Show for relying too much on internal monologuing. It’s the show’s gimmick! Enjoy it or not, that’s fine, but it’s not an automatic negative.
Others have already described the multitudinous consequences for the characters. Some that haven’t been mentioned include Buster–who was perfectly allowed to wear camouflage, just as everyday people can still wear it (and many do), actually is in “Army” (as he calls it), he signs up for a second tour of duty as a consequence of not paying attention to his so-called award ceremony. G.O.B. (not “Job”) is constantly fucking up his life – he’s tossed into prison when his escape act goes awry, gets stabbed, loses his girlfriend to his brother Michael (who then loses the same girlfriend because he can’t control his anger at G.O.B.). Lindsay suffers plenty of indignities as a result of the family’s money troubles and her constant fights with her mother, and her half-hearted attempts to cheat on Tobias aren’t successful (actually, if I were to complain about anything unrealistic, it’s the idea that someone who looks like Portia de Rossi couldn’t attract a lover!). No, there’s no major growth (though Buster had some moments of maturity and standing up for himself, and Maeby changed from not caring about her family to obviously feeling connected to them, and I don’t just mean George Michael. But show me the growth in Seinfeld? Good God, the characters there devolved if anything!
AD is much-loved by me, at any rate, because it rewards multiple viewing and careful viewership. I love continuity, I’m a whore for it, and the writers who put so much dense material into both the script and even the props that we see for a half-second on screen earn my true admiration, because that’s exactly the sort of thing that tickles me pink.
Some people don’t enjoy meta jokes, call-backs, longform jokes (the build-up to Buster’s losing his hand encompassed an entire season of foreshadowing), and so on, and that’s okay. No one has to like every form of humor. And yet somehow one can be surprised by stuff you end up liking; for example, I hate scatalogical humor and usually dislike raunchy jokes, and yet I’m a big fan of the aforementioned Peep Show and Archer (perhaps not coincidentally, the latter featuring several AD cast members), so go figure.
In the end, just accept that humor is subjective. The sooner people get that, the sooner we’ll stop having these unbelievably tedious “I DON’T FIND IT FUNNY SO PEOPLE WHO LIKE IT ARE JUST FOLLOWING THE HERD AND PATTING THEMSELVES ON THE BACK!” or, conversely, “THIS SHOW IS GENIUS AND HILARIOUS AND ANYONE WHO DOESN’T LIKE IT IS OBVIOUSLY AN IMBECILE” back-and-forth arguments.
Trust me, no one ever, in the history of entertainment discussions, has won one of these debates with such comments.
