These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Acceptable Targets: A Russian anti-satellite missile test triggers a series of Disaster Dominoes that sets back every country's space program by decades. In Real Life, China was the only country to have conducted an anti-satellite missile test that created a space debris problem, it just wasn't as serious as this.
He Panned It, Now He Sucks: An odd one with Neil Degrasse Tyson, who actually did like the movie but still felt compelled to point out its numerous scientific errors, which many fans couldn't see past.
HSQ: Extremely high. The film can almost be panic-inducing due to its relentless pacing and intense visual style.
Narm: Some of the lines can be pretty clunky. "No more just driving," anyone?
Nausea Fuel: All the spinning camera shots can make a person dizzy.
Sci Fi Ghetto: Defied. The film earned high scoring reviews from critics, became a box office smash and was nominated for 10 Academy Awards, 7 of which it won (including Best Director for Cuarón). It still played straight (albeit in less degree) in Mexico, Cuaron's homeland.
She Really Can Act: As odd as it sounds to say about an actress with a long career before the film that included an Oscar win, many had this reaction to Sandra Bullock, as she was mostly regarded as a lightweight romantic comedy star (with said Oscar being for The Blind Side, prime Oscar Bait of the maudlin kind).
Tainted by the Preview: A number of detractors and reviewers have decried the movie's "lack of scientific accuracy" based merely on the presence of sound in the trailers, and on using those same, pre-release trailers to make snap judgments about the nature of the emergency, the fact that the ISS, the Hubble, and the Tiangong are in the same orbit, or that an astronaut being flung into outer space could possibly be panicked.
