Lack of imagination. lol.
Anxiety and shock are the only emotions that this trailer tries so obviously and desperately attempts to elicit.
The trailer, which is meant to give you an idea of what the movie is about, the general atmosphere, tone, etc...and this one showcases only panic, distress, and things crashing into each other. It's comes off as gimmicky rather than geniunely thrilling (as it would have liked to).
The sports film parallel might be close (as they are generally dull), but is faulty only because the entire film isn't based around one do-or-die match much as this entire film is based around the wreckage. What counts as a "sports film"? Ali? Rocky? Prefontaine? Rudy? These are dramatic character studies. Maybe "Gravity" is too, but nothing I've seen has led me to believe such a thing.
If there is more to this movie, I won't know because the trailer has done it's damndest to pull as much anxiety out of you and get your adrenaline pumping (it's intentions are obvious) making you ask: "what if I were stuck in space and there was a wreckage", etc... The premise, and the emotions it's meant to elict are to me, weak and uninteresting.
