I'm baffled at the rave reviews. Sure, for 2013 it was visually stunning. That does not excuse the weak writing & storyline. The characters are barely developed. Bullock's character survives one implausible event after another. So implausible that frankly, the viewer's intelligence is insulted. Her emotional shift near the end wasn't believable, and the ending was lame and unsatisfying. A 7.7? Sheesh. Even a superhero movie has more depth
