Well, this was really a visually arresting movie, with all the action taking place while the rivers, forests, painted deserts and civilizations of the world rotate beneath you in the corner of the screen. It's almost 100% a two-character film, with everyone besides Bullock and Clooney being mere radio voices or figures in the distance who exit the show pretty early on, as the same disaster that sets the film in motion also takes out communications satellites. In other words, the skills of Ed Harris (as the voice of Ground Control), such as they are, are totally not needed, so he's there pretty much entirely to draw a parallel between this film and Apollo 13, but he's not getting them home this time. These two are totally on their own. Except for the whole world passing silently below. As beautiful as it is, it's totally a thriller, and reminded me of Aliens in how it doesn't bother building tension toward a climactic peak, but rather threw one tense sequence upon another bam-bam-bam through most of the movie. This is it's grace (among it's many graces really), as a character is frequently left with one chance to grab onto another or onto the hull of a ship, or be thrown off into the horror of drifting forever into space, waiting for their oxygen to run out and to die utterly alone, and I imagine carbon dioxide poisoning is a shitty way to die. But it's also a failing, as it doesn't hit as deep as it could, or wrestle much with the big questions that hovering over the planet with one's existence on the line might raise, such as 2001 or Solyaris did. (Interestingly, Clooney's last space vehicle was Solaris, an English-language remake of Solyaris.) Bullock becomes sort of a female version of a Jack London-type protagonist, a mission specialist (and therefore not a career astronaut) who starts the film overwhelmed by the challenges of space work even on a run-of-the-mill mission, but when everything goes haywire and the mission turns to survival, somehow finds a way to go on even though she has every reason to quit, and somehow finds just enough of her training stuck with her so that when calms the heck down and stops hyperventilating and gulps all her oxygen away (if you watch in 3D, you'll want to slap her), she's able, maybe, to figure out a way home. The science in it is both great the realities of pressure bursts and Newtonian momentum in space, the magic of weightlessness as she swims from chamber to chamber on the space station, or when she starts sobbing and her tears detach from her face and float out toward you in beautiful glycerin globules. and not so great All the space stations and vehicles that they hop across trying to find a way home --- their shuttle, the Hubble telescope, the international space station with a docked Russian capsule, the Chinese space station with a capsule of their own --- are not only in reasonably close proximity, but in more or less the same orbit as each other They are also in the same orbit as communications satellites, which I would imagine orbit at much higher altitudes than the International Space Station. But, while Clooney may strike some as a little oily in general and over-ingratiating in this role, if you don't root for Sandra Bullock, then you're not particularly American. (I'm not saying that this is a jingoist movie, I'm just sayin' what I'm sayin'.) This movie's a heckuva thing, even if not quite a helluva thing.
