I say maybe you should because: Have you not already decided you are going to see Gravity as soon as goddamn possible? I already did, because it's like my chest tattoo says: Alfonso Cuaron 4 Life. This is the dude's first movie in seven years (since the science-fiction classic Children of Men! which came out in 2006! TWO THOUSAND AND SIX!), so you better fucking believe I'll be there as soon as goddamn possible. (Especially when people who have already seen it are flipping the fuck out.)
In other (and fewer) words: I want to see Gravity all at once, so I've been dodging the trailers—but here's a new trailer that's so good that I just heard my revered boss, Wm. Steven Humphrey, squealing like a terrified little girl as he watched it in his office.
