I like the Dark Knight, because I watched it as a film and I didn't try to over analyze it for plausibility or directorial intent. Pretty silly, I know.
"As a film"? As opposed to what?
That's a meaningless truism, and about as mediocre an argument as I've heard (and I've heard it several times elsewhere, too).
Cue: brief, weak rant on how films are for entertainment purposes, and that anything that finds "deeper meaning" (whatever that means) is watching films for something that they're not supposed to offer.
To paraphrase Marx,
The Dark Knight is the opium of the (uneducated) masses.
