I really liked Gravity for the most part. It's a fucking marvel of special effects, just visually gorgeous all around, and the 3-D actually adds instead of detracts for once. I can't even wrap my head around the logistics of how Cuaron pulled off, like, 75% of the shots in the movie, and most of the time I honestly couldn't tell what was CGI and what was real. And a certain moment at the very end of the film (I'm sure you know what I'm talking about) is just one of the most incredibly tactile experiences I've ever had watching a movie. The whole movie was such a visceral thrill that I was actually wobbling as I left the theater as if I'd just gotten back from space myself.
Which is why it's so fucking disappointing that Cuaron (or more likely, the studio) didn't have the confidence to just let the images speak for themselves. Everything the movie works so carefully to build totally evaporates every time Bullock and Clooney open their stupid mouths to spout stupid dialogue about stupid backstories nobody cares about. Which unfortunately happens almost non-fucking-stop for the whole movie. It's all so pointless and distracting, and the movie would have worked so much better as a simple survival story. Bullock puts in a fantastic physical performance, Clooney is basically playing himself like always but that does a great job of lulling the audience into a false sense of security; both performances are hampered by the terrible script.
Such a shame, and it turns Gravity into just a very good movie instead of the truly great one it so easily could have been. Even so, this is the first movie to come out in a very long time to actually make me optimistic about the future of big-budget special effects blockbusters, so there's that at least.
