Totally agree with you on all of that. I like the Spider-Man movies, but they're about the only comic book movies I can stand. And they're pushing the envelope on that one. The LOTR lose me after about 15 minutes, too, as do the Harry Potters. I've only seen the first of both of those series, and the first 15 minutes of the second in both!
I was hesitant to see Pan's Labyrinth knowing that the director has done a couple of comic book movies, one of which I saw and *hated* (and won't mention here lest I totally dissuade you from seeing it). But it just drew me in. Very subtlely at first. Like my first Brokeback viewing, I'm kind of at a loss for words to describe it except to say, again, that I thought it was magical. And it has stayed with me since Saturday when I saw it. I keep seeing certain scenes in my head. A couple of the underworld creatures are scary as hell, but they're beautiful allegories for the very essence of the natural world (Pan, the faun) and of all unseen, dormant evil (the pale, sleeping monster). Oops - guess I'm not at a loss for words after all. But that would be one of the Seven Signs of the Apocalypse, wouldn't it?
