Saw this yesterday, really, really loved it. First two acts were perfect, little sag in the middle but then a pretty rollicking climax. Probably right up there with Incredibles and Ratatouille for most directly thematically complex Pixar work, and definitely as enjoyable as the rest of their flicks. Wall-E still holds the top spot in my heart though, because I am a big old sap for robots falling in love.
Anyway, I enjoyed this review quite a bit, much more so than the others, though I still think it got a little bit hyperbolic ("most powerful visual storytelling ever seen on film?" It was really powerful, but - EVER seen on film - that's a little much). The whole part about masculinity really was quite enlightening. I wonder when we'll see modern animated films that tackle the other side of the gender equation as thoroughly. Maybe Pixar needs to get some female directors?
Also the connections to Herzog and Conrad were very interesting - I scoffed at the sort of outlandishness of Up's premise when it was first revealed, not so much because of what it was but how it fit into what seemed like the narrative tone and framework of the story. Obviously once I saw the film that went away since there's plenty of context, but even moreso now that I consider that there have been stories like Fitzcarraldo out there.
I do have to say that, as interesting as it is to consider the parallels between a "kid's" movie like Up and things like Heart of Darkness, I'm always wary of this perspective (same goes for the argument a post above that A Bug's Life = Seven Samurai). It's almost as if we're (or maybe just I am) so insecure about giving artistic merit to these movies and how that makes us look that we need to say - hey, it's just like X RESPECTED WORK OF FILM/ART/LITERATURE - so you should respect it as much as X too.
That's bullshit, frankly. These are good movies that touch on archetypes and themes that go beyond the cultural milestones like Apocalypse Now. There's nothing wrong with pointing out the parallels like the review does - I just think it's worth saying that we shouldn't (again probably speaking for myself mostly here) feel on any level that we need to do this to justify our opinions.
